Check your usb to rs233 adapter drivers. Some if those, especially ones from Amazon and ebay come from China and require a driver from the company that produced them. Windows will recognize them as an adapter dongle but load a default driver that does not work with the chip set in the dongle. Just a thought from past personel experience. Below is the reset instructions for the 51a.

?Hi, this is Jim K6NRA.? Helping a friend out who has a ID-51A Plus. We have not been able to get the radio to xmit, as the previous discussion indicated.? I know I have the correct com port, that is, device manager matches the one used in radio preferences.? Also the cable I've been using works fine for radio programing, so I know the cable is good.? I even purchased the software from RT Systems, a lot more user-friendly than the Icom s/w.
I've checked my radio settings as per this thread, the radio via the computer will not key up.
If I use DRATS with my ICOM 92AD, works fine, of course, I had to use the special Icom cable with usb-rs-232 adaptor, so I know everything on the computer side is good.
Is there such a thing as setting the radio back to factory defaults, as I don't know what settings the owner did.
I've got a full head of hair right now, but it isn't going to last long as I keep pulling it out, I've spent lots of hours on this thing.? The only thing I didn't do is look at the RS-232 voltages going into and from the radio.
Jim
