yes. yes. Actually com4. It works with Kenwood Software using the same com port.

Did you verify in Device Manager that the cable is actually Comm 3? Did you press firmly on the cable when plugging into the radio?

No response from CHIRP after 5 minutes Re-select Download from Radio Error popup reads An error has occurred could not open port COM3: [Error 5] Access is denied
Quit CHIRP

Select Yes Writing the data to the transceiver, and radio is programmed with contents of "test" mcp file
So the problem does not seem to be with the cable or the radio, since MCP-1A can talk to the radio. So it appears that Steve and I have exactly the same problem with CHIRP. Except Steve's is first time programming and mine is after a reset or after the radio has been programmed with MCP-1A
Can any TM-281 users offer other suggestions, or CHIRP experts/developers?

I'm using Windows 10.? I previously ran Chirp to program a Wouxon hand held and it worked fine with that cable. I have a Prolific cable I got from BlueMax49ers.?? The instructions said it was a genuine Prolific chip and to use the latest drivers.? So I checked and it is using the latest drivers (3.8.28.0).? When I started Chirp, I plugged in the radio, and selected "Download from Radio".?? It gave me a dialog with Com3 preselected, and I selected Kenwood and TM281. When I clicked OK in the dialog, I get this message: _*An ERROR Has Occurred*__* *__*could not open port COM4: [Error 5] Access is denied.*_ I tried Com3, and got the same error. _*An ERROR Has Occurred*__* *__*could not open port COM3: [Error2] The System Cannot find The File specified.*_ (this may be the original error, I don't know. I changed the com port to Com4 before writing down what the original error was when it originally went to Com3) **_**_ I looked into Device Manager, and under Ports (Com and LPT) It says the Prolific USB to Serial Comm Port (Com4) I looked at the Properties and it says this: Does this sound familiar?
