Oh that so cool to hear!

Seriously it wasn't exactly hard wire/solder everything up as a bit tedious and occasionally frustrating. You could do it yourself assuming you've got a decent soldering iron & a couple of bench vices to hold stuff in place.

I've just finished making a 5m long null modem cable as well, did it "properly" with the hardware handshaking lines crossed over as per http://www.nullmodem.com/NullModem.htm. I was hoping that having hardware handshaking wired would enable me to use a baud rate > 9600 with my old 386. 

TLDR; Nope. The highest best rate that doesn't cause failures or crash the com port is 9600 baud. Turns out the UART in the multi-io card is a 16450 and so just can't do any better.

.... All stressed out, and no one to choke.
