My first guess would be that its a software issue and not hardware. The
ports should be nearly identical hardware-wise (unless you have a geoport
enabled modem port). It could be that something else (AppleTalk?) is
munging with the port. I can look at the NQC code again, but its pretty
much straight from an Apple Tech Note on using the serial ports.

Might not be a problem (for NQC). I know someone already has used a PCI
serial port card with NQC - you just need to know the right name for the
I/O drivers. Once you get the card let me know and I can talk you through
configuring NQC for it.
