EMT (EMULATE_TERMINAL) -- Emulate a dumb terminal.
usage:  EMT  [emt_command_file]


FORMAT

  EMT [pathname]


  EMT allows your node to emulate an Ascii terminal connected to another
  computer.  This asynchronous connection exists through a stream opened
  on one of the node's SIO lines.


ARGUMENT

  pathname
  (optional)       Specify file containing EMT commands.
                   Default if omitted: read standard input.


COMMANDS

STREAMS USAGE

  EMT uses the four standard streams (standard input, standard output,
  error input, and error output) as follows:

    EMT commands are read from an EMT command file or from standard input.
    The command file name may be specified on the command line or using
    the EMT 'run' command.   Up to four levels of command files may be nested.
    When EOF is reached on a command file, commands are read from the previous
    file or from standard input.  If EOF is reached on standard input, EMT
    exits.

    Keystrokes to be sent to the host computer are read from error input.
    Error input may not be redirected to a file.  Use the EMT 'xmit' command
    to transmit a file (of commands or data) to the host.  Use the EMT 'rcv'
    command to receive host transmissions to an Apollo file.

    EMT Command responses and all messages from the host are written to
    standard output.

    Error messages from AEGIS system calls are written to error output.
    Optional monitoring (MONIT) may also be written to error output (or
    to a named file).
