I'm using <br> Windows 10.? I previously ran Chirp to program a Wouxon hand held and it <br> worked fine with that cable. <br> <br> I have a Prolific cable I got from BlueMax49ers.?? The instructions said <br> it was a genuine Prolific chip and to use the latest drivers.? So I <br> checked and it is using the latest drivers (3.8.28.0).? When I started <br> Chirp, I plugged in the radio, and selected "Download from Radio".?? It <br> gave me a dialog with Com3 preselected, and I selected Kenwood and <br> TM281. When I clicked OK in the dialog, I get this message: <br> <br> _*An ERROR Has Occurred*__* <br> *__*could not open port COM4: [Error 5] Access is denied.*_ <br> <br> I tried Com3, and got the same error. <br> <br> _*An ERROR Has Occurred*__* <br> *__*could not open port COM3: [Error2] The System Cannot find The File <br> specified.*_ <br> <br> (this may be the original error, I don't know. I changed the com port to <br> Com4 before writing down what the original error was when it originally <br> went to Com3) <br> **_**_ <br> <br> I looked into Device Manager, and under Ports (Com and LPT) It says the <br> Prolific USB to Serial Comm Port (Com4) <br> <br> I looked at the Properties and it says this: <br> <br> Does this sound familiar? <br> <br> Steve <br> <br> <br></blockquote></div></div></div>_______________________________________________ <br>chirp_users mailing list <br>chirp_users@intrepid.danplanet.com <br>http://intrepid.danplanet.com/mailman/listinfo/chirp_users <br>This message was sent to Nigel Gunn, W8IFF at nigel@ngunn.net <br>To unsubscribe, send an email to chirp_users-unsubscribe@intrepid.danplanet.com</blockquote><p><br></p><div class="io-ox-signature"><p>Nigel A.
