The software is probably checking one of the pins on the serial port to see
if the modem (that's supposed to be attached) is ready. You may be able to fool
it by grounding the proper pin. I don't know which pin - you'd have to get the
pinouts of the serial connector and try each pin - but don't ground the +5 volt
and +12 volt power supply pins! (You need the pinouts to see which pins can be
grounded without damage). (I'm not sure, maybe the pin has to be held high - at
plus 5 volts thru a pullup resistor, but most of the time if the pin is not
connected to anything it will automatically go to plus 5 volts, and that's why
I said that grounding is probably required.  You also need the pinout to see
which pins are the ground pins so you can ground the other pin of your choice).
