This should be informative!

The CTTY Command of DOS 2.0 and up.

There are two ways to use the CTTY command to drive an IBM PC
with a remote terminal.

1.  Direct Connection

    When computers and terminals are configured as DTE (data
    terminal equipment), the send and receive lines have to be
    swapped. Another way is to use a null modem adapter at the
    serial cable connection.  With this connection made, type:

    MODE COM1:300,,,,

    To verify that the serial port is active and wired correctly
    to the other terminal, type:

    DIR>COM1

    This redirects the standard output of the DIR command to the
    initialized COM1 port to test the signal path. If the remote
    device sees the DIR results, you're all set. Then type:

    CTTY COM1

    Now run any DOS command from the remote terminal. When
    finished, type from the remote terminal:

    CTTY CON

    This restores control to the host IBM computer.

2.  Modem Connection

    To use a smart modem with this command, develop two batch
    files to initialize the serial port and set the modem to auto
    answer. To create the first file, type:

    COPY CON:INIT.BAT
    AT SO=1
    F6

    F6 puts an end-of-file mark, control Z, at the end of the
    file. To create the second file, type:

    COPY CON:SETUP.BAT
    MODE COM1:300,,,,
    TYPE INIT.BAT>COM1
    CTTY COM1
    F6

    To set up for an incoming call,
    simply type:

    SETUP

    You will see the running of the batch file and its messages
    up until the CTTY COM1 command. Every thing will then freeze
    up until the phone rings, the modem answers and sends the DOS
    prompt A> to the remote terminal. As with the direct
    connection, the remote can run most DOS commands, including
    ERASE *.* and FORMAT, so be careful. To return control to the
    host IBM PC again, type CTTY CON from the remote. I hope you
    have as much fun with this command as I have had.
