If you have Kermit, an AutoExec.Bat line of
Kermit Hang
will load Kermit, lower DTR, and exit, which should stop your modem 
from auto-answer.
Or, you could use a shorter program to lower DTR, but I think the load time
of Kermit is better than wasted disk space.
This assumes that your modem cable includes DTR (pin 20 at the modem), and 
that the modem is set to follow DTR.
In Microsoft C, for Comm 1:
main()
{
 outp ( 0x3FC, 0x00 );  /* 00 to turn off DTR, 01 to assert it */
 return(0);
}
