This is a hack of id's serial device driver.  It allows arbitrary baudrate,
hardware handshaking, and arbitrary irq.  This will allow you to run your
high speed modem at higher than 9600 baud.  Also, some problems with dialing
and answering the modem have been fixed.  The new structure of the modem.cfg
file is described in the accompanying modem.cfg file.

To use this fix, rename the original sersetup.exe in your doom 1.2 directory.
Copy the new file into your doom 1.2 directory, along with the sample modem.cfg.
Use as you would the normal setup.exe to launch a modem game. Play doom!
