I better choice may be to use _bios_serialcom() which
allows you to set all the standard RS232 parameters.
Of course, the port is not interrupt driven so your
program had better set up interrupts or be extremely
quick to catch all incoming characters. If you aren't
fast enough, all you will get is the last character
received. (usually just a LF or something like that)
An easier way to use COM1 for communication is to buy
a serial COM package that works with MSC. I use one
from GreenLeaf Software. It does what I need and I
believe it cost ~$200 U.S.
