I'll be going down that road in a couple of weeks. Just to be
crystal clear so I don't blow something, I have a 4-port PCI serial add
on card in my PC. 4 extra DB-9 serial ports. Is all I need is a male
to female "straight through" DB9 serial cable to connect one of these
ports to the K3/100? (i.e. no cross over - null modem), just a computer
store standard serial cable with RX/TX and GRD (pins 2,3 and 7)?
This for computer control. No USB involved in my case, so it seems
really simple. However . . . I don't want to let the smoke leak out of
anything.
