Writing data to ANY serial port from just about anything other than Basic 
(which has its own library for the purpose) is not a trivial undertaking. 
Even for COM1: and COM2:, the DOS drivers are completely inadequate. The 
BIOS is worse than useless, so you're basically left writing your own 
low-level interrupt handler. I have such a thing; if you want a copy of it 
send me mail.
