EMT/COMMANDS Aegis EMT/COMMANDS
NAME
emt/commands - Commands available once emt has been invoked.
DESCRIPTION
emt commands are read from standard input or an emt command file. The
commands are:
ae Abort on error: if an error is encountered in remote
mode, return to local mode.
asc[only] | notasc[only]
Sift out most non-printing ascii codes. Eliminates
triangles, allows bs, cr, esc, ff, lf, tab. Default
is notasc.
break n Set break duration value to n milliseconds. If set
to zero, the break key (F8) does nothing. Default is
200.
cl[ose] Close the xmit/rcv file (if open) and de-activate the
rcv filename (i.e. forget its name).
code [xx|none] emt will accept commands received on the sio line and
sent by the host. Code will define Host Command Code
to be hex value 'xx'. The host may issue any emt
command by preceding the command string with the
hex value 'xx'. The default is none, i.e. commands
are not accepted from the host.
cook[ed] Put the Apollo window in cooked mode. This makes the
input pad and the transcript pad separate windows. It
is the opposite of raw. This command does not alter
the sio line, which is ALWAYS set to raw mode by emt.
emtesc [chr|none] Set the emt escape character to chr. Use none to
disable the escape character. Default is ~ for
cooked mode, none for raw mode. The escape character
is used to send non-ascii control characters on the
sio line while in cooked mode (e.g. ^a (01) will be
sent if you type ~a). Control characters are
processed by the Display Manager when the pad is in
cooked mode. The emtesc character is also used to
emulate the typing of a function key while in cooked
mode (e.g. ~1 is equivalent to hitting F1 to return
to command mode).
{The following 3 commands are useful when running an emt command file.}
F1 Enter remote mode (Simulate Function key F1).
F2 Terminate file transfer (Simulate Function key F2).
F3 Toggle tee mode (Simulate Function key F3).
(tee mode allows xfers to/from files to be repicated
in the transcript pad. The state of tee mode is
given by the List command.)
F3 Toggle tee mode (Simulate Function key F3).
Hangup Drop dtr on the sio line; causes most modems to
hangup.
Help [tctl] Display this help information or info about tctl.
interm {cr|lf|crlf|vax|'hex_byte'}
Set the input line-termination sequence that the host
will send. Default is crlf. 'hex-byte' can be any
one-byte hexadecimal value. Different hosts
terminate lines with different combinations of cr and
lf. Setting interm correctly to correspond with what
the host is tranmitting will eliminate double-spacing
or multiple messages on one line when receiving from
the host.
outterm [cr|lf|crlf|'hex_byte']
Set the output line-termination sequence to be
transmitted to the host. Default is cr. Different
hosts require different terminators to operate
correctly. Note that when running emt windows
between two Apollo's, you should set interm and
outterm compatibly.
line [1|2|3|pname] Select the SIO line. Default is line 1
(/dev/siO1).
List Display the current SIO line, all emt switch
settings and the receive filename, if any.
monit [monit_file] Write every character received over the SIO line
to previous specification or errout is used.
nomonit Stop monitoring.
q[uit] Exit from emt.
raw [-echo|-noecho] [-lf|-nolf]
Put the Apollo window in raw mode. This causes the
input pad and the transcript pad windows to be merged
into one window. It is the opposite of raw. This
command does not alter the sio line, which is ALWAYS
set to raw mode by emt. The option -echo means echo
keystrokes to standard output (the Display Manager
does not automatically echo keystrokes in raw pads).
-lf means convert cr to lf for echoed lines and is
used to prevent overwriting in the pad. Default is
-noecho -nolf.
rcv [-r] [-keys|-nokeys] [pathname]
Receive transmissions into the file named by
pathname. Receive begins after the rcv command is
issued, when remote mode is entered (F1). If no
pathname is specified, it uses the previous name, if
any.
-r means replace existing file.
-keys means write keystrokes to file along
with received data. Default is -nokeys.
run [cmd_file] Read emt commands from the named file. Command
files may be nested to a level of four and may
contain any emt command or comment lines starting
with #.
tctl [tctl commands]
Pass this command line to tctl to configure the
SIO line. It is not necessary to specify the line
number (-line), although you may if you wish to
operate on a different line than the one you are
using.
xmit pathname Transmit the file named by pathname to the
host. Tranmission begins when remote mode is entered
(F1).
FUNCTION KEYS
In addition to the commands listed above, emt redefines the following
function keys:
F1 = Switch between Local and Remote modes.
F2 = Terminate file transfer (xmit or rcv) and close the file.
F3 = Toggle tee mode.
tee mode allows xfers to/from files to be repicated
in the transcript pad. The state of tee mode is
given by the List command.
F8 = Send a BREAK to the host. Valid only in remote mode.
^F7 = Display a picture of the function key definitions.
These function keys may be simulated by typing the emtesc character followed
by the function key number (e.g. ~1 for F1). When emt is used from the
vt100 emulator, F1-shifted is used instead of F2, and F1-control is used
instead of F3.
