HI I have tried several rig control programs and so far I can't get a single one to work. The kenwood Ts870 is connected by either a serial to usb adapter or an actual serial controller card on the pc. So far none of the programs can find the radio. I have matched port speed parity and com ports and still nothing. This is the usual result with all three flow control options tried at one point or another. Has anyone got this radio to work under computer control?
