I am trying to program my Kenwood TM281 for the first time. 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>
