COMM_MON.EXE is an OS/2 program that can be used to visually monitor 
the activity by a communications program.  This program reads characters
coming in from two comm ports and sends any characters read from
either port out the other port.

The usage of COMM_MON is as follows:

    COMM_MON <devnam1> <devnam2> <baudrate>

where:

    <devnam1>,<devnam2>     - These are the names of the
                              communications devices to use for the
                              monitoring process.  These should be
                              ASYNC devices such as COM3, etc.

    <baudrate>              - This is the speed that the program
                              should talk to the communications
                              devices, for instance, 1200, 2400,
                              9600, etc. (Note: the port is set to
                              8 data bits, 1 stop bit, and no
                              parity).

COMM_MON prints to standard output so the program can be used in a
PM window, a full-screen window, or the output may be redirected to a
file.  You can stop the program by pressing Ctrl+Break.

For example, I have a 8-port DigiChannel (from DigiBoard) on which I
run a communications program.  I use two of these ports to monitor
the activity on another port by wiring my board as follows:

    ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿                ÚÄÄÄÄÄÄÄÄÄÄÄ¿
    ³DigiChannel   ÃÄÄÂÄÄcom3ÄÄÄÄÄÄÄ´Hayes ModemÃÄÄÄÄùùù Phone Line
    ³PC/8i         ³  ³             ÀÄÄÄÄÄÄÄÄÄÄÄÙ
    ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ  ³              ÚÄÄÄÄÄÄÄÄÄÄ¿
                      ÃÄÄcom4ÄÄÄÄÄÄÄÄ´Null ModemÃÄÄÄÄ¿
                      ³              ÀÄÄÄÄÄÄÄÄÄÄÙ    ³
                      ÃÄÄcom5ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ
                      ³
                      .
                      .
                      .

After the DigiChannel is set up, I run the COMM_MON program as
follows:

    COMM_MON COM3 COM4 9600

Finally, I run my application attached to COM5.  Any characters sent
or received from the modem or my application will be printed by the
COMM_MON program and echoed on down the line.

COMM_MON is released as free-ware.  You may use the program as you see
fit though it may not be sold.  Please direct questions or comments
