NAME
vterm - Creates a virtual terminal emulating a VT220 series terminal
SYNOPSIS
vterm -l ttx# [flag ... ]
vterm -shell [flag ... ]
vterm -a aux# [flag ... ]
vterm -n nodename [flag ... ]
vterm -N nodename [flag ... ]
vterm -x{s|r|e} command
FLAGS
The only required flag for vterm is the host type. One, and only one,
host type may be specified:
-a aux#
Creates and connects a vterm window to a serial device through
auxiliary (RS232) port aux# on the local host. An auxiliary port
number must be specified, and may have the value 0, 1, or 2. For
example, if there is a modem connected to auxiliary port 2,
creating a virtual terminal with the -a 2 flag causes the virtual
terminal to behave like a terminal connected directly to the modem.
-l ttx#
Creates and connects a vterm window to the CLIX operating system of
the local workstation. If the ttx# option is specified, vterm
attempts to connect to device ttxttx#. If no ttx# is specified,
vterm connects to the lowest-numbered available ttx device. The
ttx# can range from 0 to 18. This option is not available on
systems running CLIX-TS.
-n nodename
Creates and connects a vterm window to a remote host on the LAN or,
through a gateway, to a host on another LAN using the XNS visit
program. The Ethernet address (for example, 08-00-36-d8-8a-00) or
nodename (for example, wilma) of the remote host must be specified.
-N nodename
Creates and connects a vterm window to a remote host on the LAN or,
through a gateway, to a host on another LAN using the TCP/IP telnet
program. The Internet address (for example, 129.135.226.195) or
nodename (for example, fred) of the remote host must be specified.
2/94 - Intergraph Corporation 1
vterm(1) CLIX vterm(1)
-shell Creates and connects a vterm window to the CLIX operating system of
the local workstation to the lowest-numbered ttx device available.
This option also works on systems running CLIX-TS.
-x{s|r|e} command
Creates a vterm window and executes the specified command string.
If the command string contains embedded spaces, the string must be
enclosed in double-quotation marks ("").
The -x modifiers (r, s, and e) specify conditions which prevent the
vterm window from being deleted after completion of the command.
If none of the modifiers are specified, the virtual terminal is
deleted upon termination of the command.
-x command Executes command if created with no modifier. Upon
completion of the process, the window is deleted
automatically.
-xe command Causes the window to stay on screen if an error occurs
while executing the command. Otherwise, the vterm
window is deleted automatically.
-xr command Causes the window to remain on screen and the command
to be executed repeatedly until the user deletes the
window.
-xs command Causes the window to remain on screen after executing
the command, until the user deletes the window.
Other available flags include the following:
-c Specifies that the vterm window supports changing of screen colors
through DEC ReGIS control sequences, the Intergraph regis command,
or ANSI escape sequences.
-collapse xy
Creates a vterm window that initially appears on the screen in its
collapsed state. The x and y coordinates define the initial screen
position of the upper left corner of the collapsed window (for
example, -collapse 1100 750).
-console
Specifies that the vterm window is to act as the system console.
There can only be one system console. The -console flag is valid
only when creating a local (-l) window. The -console option is not
available on systems running CLIX-TS. On CLIX-TS systems, the
console window can be created only from the workstation menu.
-f catfile
Causes the vterm window to use the saved characteristics of a
previously-defined window catalog file catfile to describe the
2 Intergraph Corporation - 2/94
vterm(1) CLIX vterm(1)
attributes of the vterm window being created.
Window environment files, or catalog files, are created in the
Catalog menu. (See "Catalog Icon" in the User Interface section.)
-log logfile
Appends a copy of every line typed or displayed onto the end of the
file logfile. A vterm command does not record every character
typed in or received from the host; when it receives a newline,
linefeed, formfeed, or vertical tab from the keyboard or host, it
saves the characters displayed from the beginning of the current
line (the line on which the cursor currently resides) to the end.
-origin x y
Specifies the original screen position of the vterm window. The x
and y parameters are the horizontal and vertical coordinates of the
upper left corner of the window. By default, a vterm window is
created at (41,34) (for example, -origin 10 300).
-p aux#
Treats the auxiliary port aux# as if it were a printer connected to
a VT220 auxiliary port. For example, vterm -l -p 1 will create a
vterm window connected to a local host and will treat any device
connected to auxiliary port 1 as a dedicated printer.
From a vterm window created with the -p flag, the <Print Screen>
membrane key can be used to dump the text currently displayed to
the printer. The auxiliary printer can also be used as a logging
device, or can be controlled by an application running in the vterm
window. (See the Printer Setup Menu in the User Interface
section.)
If a vterm is created with both the -a and -p flags, the auxiliary
ports specified must be different.
-passive
Specifies that the vterm window does not become the active process
until it is explicitly activated by the user. By default, a newly
created vterm window will become the active process.
-s symfile index
Declares a collapse icon to be used instead of the standard Environ
V collapse icon.
The symfile file is the Environ V symbol file which contains the
icon, and index is the symbol's index number in that file. For
example, a vterm window created with the following will have a
collapse icon resembling a VT220 terminal:
vterm -s /usr/ip32/vt200/vt220.icon 0
2/94 - Intergraph Corporation 3
vterm(1) CLIX vterm(1)
-show Causes a collapsed window to uncollapse and pop-to-top whenever
vterm receives a linefeed from the host.
-size x y
Overrides the default size of the vterm window. The values of x
and y determine the size of the window (in pixels) when it is
created. By default, a large vterm window is 1004 x 526 pixels
(for example, -size 1004 750).
-small Creates a scaled-down vterm window. The -small window still
displays the same 24 rows of 80 columns, but uses a smaller
character font, thus the smaller size (604 x 407).
-T title
Allows the title of a vterm window to be customized. For example,
the following will create a local window titled ``HomePlate'':
vterm -l -T "HomePlate"
By default, the vterm window's title is the name of the host or
device to which the vterm window is connected, followed by a dash
and ``VT220''. For example, a vterm window connected to network
node fred would be titled ``fred - VT220''.
The title of the Console window (created with the -console flag)
cannot be overridden.
-t device
Causes the vterm window to request a specific device logical name.
Otherwise, the host will assign the first available device to the
vterm window.
If the remote host is running CLIX, device is the device number of
the remote terminal device through which the vterm window will try
to connect. (For example, specifying flag -t 5 would correspond to
the terminal device /dev/ttn05).
If the host is running VAX/VMS, an XT device name becomes
associated with the logical name device.
The -t flag is valid only for network vterm windows (created with
the -n flag).
-u username[.password]
Specifies a username and optional password under which the vterm
window will execute. If a password is required but not specified,
the user is prompted for a password. The -u flag is only valid for
windows created with the -x flag.
DESCRIPTION
4 Intergraph Corporation - 2/94
vterm(1) CLIX vterm(1)
The vterm command creates an Intergraph window-based virtual terminal
which emulates a DEC VT220 series ASCII terminal. The vterm command
allows a user to connect to one of three classes of hosts: the local CLIX
operating system, a remote host over a local area network (LAN), or a
serial device connected to one of the workstation's auxiliary ports.
Using the -x flag, vterm can also temporarily create a window to execute a
command.
The vterm command treats data typed in from the keyboard and data output
to the window's display as a DEC VT220 would. When not the active
process, the vterm command still displays data and performs escape
sequences sent from the host to vterm, but does not process keyboard
input.
Through it's flags and setup menus, vterm also provides the user-
configurable features of a DEC VT220.
The vterm command requires the following software and hardware:
⊕ CLIX operating system
⊕ Intergraph graphics software (Environ V)
⊕ A graphics display
⊕ Network software (Intergraph Network Core (INC))
User Interface
A vterm window has three parts: the display area, the scroll bar, and the
window control strip.
The display area
The display area is the large part of the window that is analogous
to the screen of a VT220 terminal. Characters received from the
host are displayed there, including those echoed back to vterm from
the host, if it is programmed to do so.
Escape and control sequences will produce the same effect in the
display area as they do on a VT220.
The scroll bar
The vterm command can be configured to save data as it is scrolled
off the top of the vterm display. This data is stored in the
scrollback buffer, which can be viewed using the scroll bar on the
right side of the vterm window.
Lines of text are saved in the scrollback buffer as they are pushed
off the top of the window by a linefeed or formfeed.
The window control strip
2/94 - Intergraph Corporation 5
vterm(1) CLIX vterm(1)
The vterm window and setups are controlled using the icons in the
window control strip. When invoked (by clicking on them with the
middle mouse button), the icons either perform their pre-defined
function or invoke a setup menu, where terminal characteristics may
be viewed or modified.
Window Control Strip Icons
Delete Icon
The delete icon, which looks like an ``X'' inside of a square, and
appears at the far left of the window control strip, will delete
the window and kill the vterm process.
RS232 Icon
The RS232 icon appears only when a vterm window has been created
with the -a flag, or a printer port has been specified with the -p
flag. The icon resembles a side view of a workstation with an
RS232 cable trailing out the back. Clicking on this icon will
bring up the RS232 Port Setup menu. (See Setup Menus.)
Setup Icon
The setup icon, which looks like a front view of a workstation,
will invoke the main setup menus. These allow the user to change
or set up terminal features and characteristics. (See Setup
Menus.)
Catalog Icon
The catalog icon, which resembles a file folder, allows you to save
the terminal environment in a file for later use, or to load a
terminal environment file saved from a previous vterm session. A
terminal environment file can also be deleted from this menu.
The terminal environment saved in the catalog file includes all the
configurable options in the setup menus, the macro strings, the
size of the window, its position, color tables (if a color vterm
window), and whether it was created with the -collapse flag.
Reset Terminal Icon
The reset terminal icon, which looks like a window with a check
mark in it, resets all terminal settings to vterm default states,
sets the display attributes to normal, clears the display area, and
moves the cursor to the home position.
Resize Window Icon
The resize window icon has arrows pointing to all sides of a small
window. When this icon is selected, the window reverts to the
default size, which is 80 (or 132) columns wide and 24 lines deep
(in pixels, 1004 x 526 for a normal window and 604 x 407 for a -
small window).
Clear Screen Icon
6 Intergraph Corporation - 2/94
vterm(1) CLIX vterm(1)
The clear screen icon clears the vterm display and moves the cursor
to the home position. The icon itself resembles a cleared window,
with just a cursor displayed. Use of the clear screen utility does
not affect the scrollback buffer; however, the data on the vterm
display when it was cleared will not be saved in the scrollback
buffer.
Modify Icon
The modify icon, which resembles the four points of a compass, is
used to move and resize the window.
Pop-to-Top Icon
The pop-to-top icon, which looks like a solid rectangle stacked on
top of two dotted-line rectangles, brings one window in front of
all other windows.
Pop-to-Bottom Icon
The pop-to-bottom icon, which looks like a solid rectangle with two
dotted-line rectangles stacked on top of it, is used to move the
top window behind all other windows.
Collapse Icon
The Collapse Icon, which looks like a small off-center square
connected with lines to the corners of a surrounding square, is
used to toggle the window between its normal state and its
collapsed state.
Editing Controls
A vterm window has two separate copy and paste facilities that allow the
user to select and then copy text from a vterm window to the same window,
a different vterm window, or to any application that uses the Environ V
scrap facility.
Text in the display area or in the scrollback buffer is selected using the
pointer (mouse or puck). To select text, first position the arrow at one
end of the text to be selected (either the first or last character).
Pressing and holding the middle button down, drag the arrow over the rest
of the text to be selected and release the button when all of the desired
text has been highlighted.
There are two mutually exclusive copy/paste mechanisms available to the
vterm user. The first is the quick paste facility, which will only copy
and paste text located in the same vterm window as the currently selected
text. To quick paste, click the left button. The selected text will be
copied and pasted to vterm as though it were typed from the keyboard.
Selecting another block of text or unselecting a highlighted block will
empty the quick paste buffer.
Another way to copy and paste text is by using the Environ V scrap
facility. Clicking on the copy icon will place the selected text in the
2/94 - Intergraph Corporation 7
vterm(1) CLIX vterm(1)
scrap, where it will remain until overwritten by another copy to the
scrap, which may be done by any application. By clicking on the paste
icon of any active window, the scrap will be pasted to the window as
though it were typed from the keyboard.
Copy Icon The copy icon, which looks like a window with an arrow
pointing up and out of it, is used to place selected text in
a special buffer, called the scrap, for later use.
Paste Icon The paste icon, which looks like a window with an arrow
pointing into it, sends any text in the scrap to the host as
though it were typed from the keyboard.
Setup Menus
A setup menu is opened when the Setup key is pressed, the setup icon is
clicked or, in the case of a vterm window created with -a or -p flags,
when the RS232 icon is clicked (in which case only the RS232 Port Setup
menu is invoked).
Below are descriptions of the functions and options available through
these two menus. Where applicable, default values for terminal
characteristics are enclosed in brackets ([]) following the description of
the attribute.
The RS232 Port Setup menu has the following configurable options:
Port # Auxiliary/Printer
Identifies which port number the information on the rest of the
menu applies to and how the port is used. For instance, the RS232
Port Menu for a vterm window created with vterm -l -p 2 will
display Port 2, with the printer item selected, and the auxiliary
item disabled.
If a vterm window connected to an auxiliary host (-a flag) is also
connected to a dedicated printer (-p flag), the RS232 Port Menu
will reflect the status of the port selected in this field.
Baud Rate
Specifies the rate at which vterm transmits and receives data to
and from the host. Valid baud rates are 50, 75, 110, 134.5, 150,
200, 300, 600, 1200, 1800, 2400, 4800, 9600, and 19200 (available
on most systems) [9600]
Parity Specifies what parity checking/generation will be supported. Valid
parity choices are None, Odd, and Even. [None]
Data Size
Specifies the number of data bits in each character. 5, 6, 7, or 8
data bits may be selected. [8]
8 Intergraph Corporation - 2/94
vterm(1) CLIX vterm(1)
Stop Bits
Specifies the number of stop bits in each character (1 or 2). [1]
Auto XON/XOFF
Enable or disable the generation of XON/XOFF flow control. [ON]
Incoming XOFF
Enable or disable the execution of incoming XOFF commands. [ON]
Auto RTS/CTS
Enable or disable bidirectional RTS/CTS flow control. [OFF]
The main setup menus are described below. Clicking on the setup icon or
pressing the Setup membrane key will invoke the other setup menus.
Different kinds of attributes can be set by selecting an appropriate menu
from the menu list at the right side of the Setup Menu.
General Setup
Emulation
Specifies whether the vterm window currently emulates a
VT100 or a VT220 terminal. [VT220]
Data Size
Specifies whether vterm recognizes only ANSI standard 7-bit
control codes (7 Bits) or recognizes both the 7-bit codes
and the extended 8-bit codes (8 Bits). [8 Bits]
Note that if the vterm window was created with the -a flag,
the Data Size option in the RS232 Port Setup menu must also
be set to 8 bits before the extended 8-bit control codes
will work.
Erase Extent
Specifies what part of the screen will be cleared by a clear
screen command. Either the entire screen (Page) or an area
defined by margins set by escape sequences (Margins) can be
set to be cleared. [Page]
Form Feed
Specifies how the terminal will respond to a formfeed from
the host. If Line Feed is specified, the display will
scroll one line. If Home & Clear is chosen, the displayed
screen will be cleared and the cursor moved to the upper-
left corner of the display. [Line Feed]
Online Specifies whether the vterm window is online or offline.
When the vterm window is online, vterm communicates with the
host. When not online, the vterm does not transmit or
receive data to or from the host, and characters typed on
the keyboard are echoed to the screen as in Local Echo.
2/94 - Intergraph Corporation 9
vterm(1) CLIX vterm(1)
[ON]
In some instances, such as when entering escape sequences to
change the colors on a color vterm window, the window must
be placed offline.
Local Echo
Displays a typed character, when Local Echo is turned on, in
the vterm window's display area as it is sent to the host.
When local echo is off, a typed character is sent only to
the host. If the host is programmed to do so, it will echo
the character back to vterm, which then displays it. [OFF]
New Line
Specifies how the host and vterm are to interpret newline
commands. If on, a carriage return followed by a linefeed
makes up the newline command. Otherwise, a single carriage
return is the newline character. [OFF]
User-Defined Keys Locked
Specifies whether or not the host can download User Defined
Key (UDK) definitions to vterm. When locked, the key
definitions are prevented from being downloaded.
UDKs are used by some applications to assign a device
control string to the programmable function keys on a VT220.
UDKs are not the same as vterm macros, which allow the user
to assign a character string to any key on the workstation's
keyboard. [OFF]
Log File
Specifies a file (by default, /usr/tmp/log) into which
displayed lines are logged. [OFF]
Buffered Screens
Specifies the number of screens saved in the scrollback
buffer.
If zero screens are specified, data is lost as it scrolls
off the top. When zero screens are specified for the
scrollback buffer, the scroll bar disappears.
If the number of buffered screens are decreased, the newest
lines in the buffer are preserved. For instance, if the
number of buffered screens is decreased from 20 to 15, the
data saved in the oldest (toward the top of the buffer) 5
screens are deleted. [10]
Display Setup
10 Intergraph Corporation - 2/94
vterm(1) CLIX vterm(1)
Cursor Visible
Specifies whether or not the cursor is visible. [ON]
Cursor Blinking
Specifies whether or not the cursor is blinking. [OFF]
Block/Underline
Specifies a block cursor or an underline cursor. [Block]
Columns
Specifies 80- or 132-column display.
The size of the window does not change when toggling between
80- and 132-column displays; the window uses a smaller font
to display the text. Since a window created with the -small
flag already displays characters in the smaller font, the
window must be resized by the user. [80]
Autowrap
Causes an automatic return and linefeed when the cursor is
at the end of the display line when on. Thus, the next
character is displayed in the leftmost column of the next
line. Otherwise, characters beyond the right margin will be
written in the last character position of the current line.
[ON]
Display Controls
Causes control characters sent by the host to be displayed
but not interpreted when on. Otherwise, control characters
are interpreted but not displayed. [OFF]
Jump Scroll
Not implemented. [OFF]
Light Background
Displays dark characters on a light background when on.
Otherwise, light characters are displayed on a dark
background. [OFF]
Erase Screen On Column Change
Selects whether data is erased or preserved when the display
is toggled between 80 and 132 columns. [OFF]
Keyboard Setup
Warning Bell
Produces a bell sound if on, when it receives a <Ctrl-G>
character. [ON]
Auto Repeat
Causes a character to be repeated if on, for as long as the
2/94 - Intergraph Corporation 11
vterm(1) CLIX vterm(1)
key for that character is pressed and held down. [ON]
Answerback
Sends an answerback message to the host upon receipt of an
ENQ code. [Hello World!]
Once the answerback message has been entered, the Concealed
checkbox may be turned on to hide the message from the user.
Otherwise, the answerback message will be displayed in the
menu. Once the answerback message has been concealed, it
cannot be ``unconcealed.'' However, a new answerback
message may be entered. [OFF]
Cursor Keys Normal/Application
Sends either of two sets of escape code sequences to the
host depending on how the cursor keypad is configured. In
Normal mode, the cursor keys generate ANSI cursor control
sequences. In Application mode, the cursor keys generate
program control functions for the application. [Normal]
Keypad Numeric/Application
Generates, when in Numeric mode, the numeric characters,
commas, periods, and so on, that appear on the keypad keys.
In Application mode, those keys generate escape code
sequences for the application to use (perhaps as function
keys). [Numeric]
Tab Setup
Tab stops may be set manually from this menu by clicking on the
numbered box of the column. The horizontal scroll bar can be used
to access columns not currently displayed in the configuration
window. Default is 8-column tabs.
Tab Motion
Fills all characters between the current cursor position and
the next tab stop with spaces when the Spaces option is
specified. With Direct motion, a tab character (the <Ctrl-
I> sequence) is inserted, which moves the cursor directly to
the tab stop without inserting additional characters.
[Direct]
Clear Tabs
Removes all tab stops.
Set 8-Column Tabs
Clears all tab stops and sets new tab stops in 8-column
increments.
Printer Setup
Printer Attached
12 Intergraph Corporation - 2/94
vterm(1) CLIX vterm(1)
This checkbox is informational only. If checked, the window
was created with the -p flag. If not checked, no printer is
attached and no values in this menu may be changed.
Printer Mode
Normal Allows the operator to invoke <Print Screen> from the
keyboard.
Auto Prints the current line of data as the cursor is
moved off the line (similar to file logging).
Controller
Provides the host with direct control of the printer.
All data received from the host is sent directly to
the printer and is not displayed in the vterm window.
[Normal is the default Printer Mode]
Terminator None/Form Feed
Selects whether or not a formfeed is sent to the printer
after a page is printed. [None]
Macro Setup
A macro is a character string that can be assigned to any key on
the keyboard. For example, a macro could be defined to key in
Intergraph whenever the <A1> membrane key is pressed.
The macro menu consists of a button representation of the entire
keyboard, a macro key-in, a backspace button, and a button that
clears all macros.
To set up a macro, click on the button representing the key for
which the macro is to be assigned, then type in the macro string.
A macro may be a maximum of 127 bytes in length. A byte is
generally equivalent to one character.
Clear All
Clears all currently defined macros after verification.
backspace
Provides the delete function when using this menu. The
backspace button is a small button between the macro key-in
and the Clear All button. This must be used instead of the
delete key when typing macro definitions. Since every key
pressed becomes part of the macro string, pressing the
delete key to backspace over a mistyped character does not
delete the last character typed; rather, it leaves that
character in the macro string and places the ASCII code for
the delete key in the string right after it.

FILES
/usr/tmp
The default directory for log files. If a full pathname is not
specified, log files are placed in /usr/tmp. The default log file
is /usr/tmp/log.
/usr/ip32/vt200/catalog
The default directory for catalog files.
/usr/ip32/vt200/aux
The directory that holds the default setups for the auxiliary
(RS232) ports.
/usr/ip32/vt200/font
The font directory for vterm.
/usr/ip32/vt200/console, /usr/ip32/vt200/vt220.icon
Environ V format symbol files that hold the collapse icons for the
console and VT220 windows, respectively. Each file contains one
2/94 - Intergraph Corporation 15
vterm(1) CLIX vterm(1)
symbol with an index of 0.
EXAMPLES
1. The following example creates a small local vterm console window.
When created, it will appear in its collapsed window form in the
bottom right corner of the workstation. It will not be the active
process and will uncollapse when it receives a linefeed. This command
will not work on systems running CLIX-TS.
vterm -l -console -passive -collapse 1119 765 -small -show
2. The following example creates a color vterm window named ``Home
Window''. The serial device attached to RS232 port 0 will be treated
as a dedicated printer. This command will not work on systems running
CLIX-TS.
vterm -l -c -p 0 -T "Home Window"
3. The following example creates a vterm window connected to its host
through auxiliary port 2. The environment saved in the file
/usr/ip32/vt200/catalog/greenterm will be used to set up the vterm
window.
vterm -a 2 -f greenterm
4. The following example creates a vterm window connected to the host
Fred on the LAN. The session will be logged in the file
/usr/tmp/Fred.log.
vterm -n Fred -log Fred.log
