Once you get to an RS-232 interface (USB adapter of some sort - watch
out for the counterfeit ones!), the easiest way to get to the 736R is
the simple TTL adapter from Manfred, XQ2FOD. Just takes 3 parts! See
the file "RS232SIM.GIF" in http://ludens.cl/Electron/fodtrack/DRAWINGS.ZIP
I've used it for many years with a variety of tracking environments from
FODTrack in DOS to GPredict in Linux.
