Re: [chirp_users] Error Programming Kenwood TM281

I'm having the same problem Steve Thomas has: Windows 10 PC Radio Kenwood TM-281 Cable - Prolific USB-to-Serial Comm Port (COM3) Driver 3.2.0.0 7/31/2007
Run CHIRP daily-20190222 Select Download from Radio Confirm Radio & Port
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
Open MCP-1A
Select Read>All Reading the data from the transceiver, and data is displayed in window Select File>Open - choose "test" mcp file. Full programming data is displayed Select Write>all Popup asks "Do you want to write the data to the transceiver?" 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?

Mine works fine under Linux using the Kenwood supplied cable and generic USB/serial adaptor but remember that that radio programmes in real time/live mode so you can't download and save an image. It re-saves every change you make in real time.

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?
