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.

(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.


on it's own as a comparison!  ;-)


    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

    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..)
