Can anyone give me an idea of what is involved in talking to the com1 port?

I have an HP Vectra (286 ibm compatible) with a serial port connected to
a Hayes smartmodem 2400.   The Hayes modem likes to hear commands like
ATD, ATs8=7, ATL, and ATDT0xxxxxxxxxxxx.   I would like to give it such
commands directly from DOS.

Also, my host system is connected to a DEFENDER unit, and I use my company's
ATT credit card number to dial the system.  Therefore, the number I dial
is of the sequence:

        ATDT04879247,21578680288887,,,1048882#,#
            ^^^^^^^^ ^^^^^^^^^^^^^^   ^^^^^^^^
            phone#   credit card #    defender code

  Where each "," indicates a configurable (in seconds) delay.  This is 40 
characters long(it could be even longer if I had to dial 9 to get out), and
I have not found a communications package that will dial such a number 
for me.  I used Mirror, and couldn't get it to send AT commands directly, 
nor could I get it to send a string this long.

In anyone has any ideas or suggestions, I would appreciate it.
