Good...

rick@rick-ham ~ $ ls /dev/ttyU** ls: cannot access '/dev/ttyU**': No such file or directory? << with

That should be

ls /dev/ttyU*            (One star!   Some spurious ones appeared as a result of me trying to be clever..)

Also try...

dmesg | tail             Immediately after connecting the (powered up) radio and lead, or your Prolific based lead.

Example...

dave-XPS-L502X ~ $ dmesg | tail [  504.731848] usb 2-1.2: Product: US232R [  504.731853] usb 2-1.2: Manufacturer: FTDI [  504.731857] usb 2-1.2: SerialNumber: FTDBHZL8 [  504.733883] ftdi_sio 2-1.2:1.0: FTDI USB Serial Device converter detected [  504.734055] usb 2-1.2: Detected FT232RL [  504.734063] usb 2-1.2: Number of endpoints 2 [  504.734071] usb 2-1.2: Endpoint 1 MaxPacketSize 64 [  504.734079] usb 2-1.2: Endpoint 2 MaxPacketSize 64 [  504.734085] usb 2-1.2: Setting MaxPacketSize 64 [  504.734681] usb 2-1.2: FTDI USB Serial Device converter now attached to ttyUSB0 dave-XPS-L502X ~ $

(That was after connecting a FTDI based USB<>Serial adapter.)

If you do:-

dmesg | tail -20

You'll get the last 20 lines of the dmesg output.   Without the -20 (or other number) you'll get 10 lines by default. Try:-

dmesg

on it's own as a comparison!  ;-)

See:-

man tail

for details of the tail filter.

~~~

If you have the radio's user manual, and it has all the CAT commands etc described, install "cutecom"  A nice little graphical serial terminal program...

sudo apt update && sudo apt install cutecom        Should do the trick.  (You'll only be asked for your password once.)

(Launch it from the command line with just    cutecom    or find it in the "Other" menu choices from the Mint menu button, at least that's where it is on this box.)

Then you can try to manually communicate with the rig, to try out the interface.   That can be another "steep learning curve" but it'll do you good to learn how to do such things for the future, especially with bit rate, data bits, parity and so on.

Hope something helps.

PM me if you need to keep from QRM'ing the list.   (I've Bcc'd you direct so you can reply direct if needed..)
