Working with this 486 motherboard: https://www.elhvb.com/mboards/chicony/ch471b/ch-471b.html
It has two onboard 10-pin COM connectors, but my serial port has a 9-pin ribbon cable. I'm not sure of the history here but is there any easy way to rewire the serial cable to work with a 10-pin connector so my serial mouse works?
