EMT/COMMANDS -- Commands available once EMT has been invoked.      84/04/20


  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.

  ASConly | NOTASConly   Receive only valid ascii codes. Others are sifted out.

  BREAK  n               Set BREAK duration value to  n milliseconds. If set to
                         zero, the break key (F8) does nothing. Default is 200.

  CLose                  Close  the  file (if open)  and  de-activate  the  RCV
                         filename (i.e. forget its name).

  CODE [xx|NONE]         Define Host Command Code to be Hex value  xx. The host
                         may issue any emt command  by  preceding  the  command
                         string with the character 'xx'.  The default is  NONE.

  COOKed                 Put the Apollo terminal in cooked mode.

  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 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).

  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.  Formerly TERM.

  OUTTERM [CR|LF|CRLF|'hex_byte']
                         Set the output line-termination sequence to be
                         transmitted to the host.  Default is CR.

  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
                         'monit_file'.   If  a filename is  not  specified, the
                         previous specification or errout is used.

  NOMONIT                Stop monitoring.

  Quit                   Exit from EMT.

  RAW [-ECHO|-NOECHO] [-LF|-NOLF]
                         Put the Apollo terminal in raw mode.  -ECHO means echo
                         keystrokes  to standard output.  -LF means  convert CR
                         to LF for echo'd lines.  Default is -NOECHO  -NOLF.

  RCV [-R] [-KEYS|-NOKEYS] [pathname]
                         Receive transmissions into the file named by pathname.
                         Receive begins when remote mode is entered (F1). If no
                         pathname is specified, use 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.
   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.
