[Fx: slaps forehead]
At my advanced age, I should know better. Having installed the udev file, it now works as expected.
Always read the warnings. Then, read them again. Do NOT assume that what you once knew is still valid...
Obviously, it fixed the problem, which probably was a permissions thing. The /dev/ttyACM0 permissions are rw-rw-rw- as opposed to rw-rw---- but as the user is a member of the dialout group it "shouldn't" matter, but clearly does, unless the other things the rule does:are significant. My udev expertise is (clearly) non-existent, and as far as I can determine, means that that something somewhere in the device installation/notification chain is being told to ignore a couple of things. Would be nice to know, but not essential.
Since this resolves my issue, my frustration levels are significantly lower. Now I just have to try and port the code. I suspect for the Pico W this will be relatively easy, unless I run out of RAM during execution, but the WizNet will be more of a challenge in some ways (as there is no WiFi stuff), but simpler in others, in that there is no WiFi stuff - so no need to configure SSID and password for a start. Providing I can see a DHCP server somewhere I can take it from there![:)]( "Smile")
Thanks for the appropriately timed kick up the rear - like I say, at my age I should know better, but of course, at my age, I thought I knew what I was doing...
