Thanks Sean for that help. I’m tangled up in Holiday Domestic Duties at the moment but will give it a try in the new year. Meantime questions rolling around my head; if I’m writing the LC prog on a Mac do I have to designate the (PC) com port in that code, which I’m thinking would mean it couldn’t be tested right there and then on the Mac? Also, I’m toying with the idea of using an Arduino as my I/O device. Does that sound healthy?

Season’s greeting to all the list. best, Alex

Hi Alex
Welcome!
I've done exactly and very similar to what you are describing about 6yrs
ago from Mac, PC, Linux, iOS via USB, WiFi and GPRS serial adapters. For
lighting up miniatures of housing estates and apartment blocks. And then
for some film miniatures for toy commercials and so on.

Once you've installed the driver for your adapter on Win10, go to the
Device Manager, Ports and find out what COM port it's linked to (eg, COM2).
Now in LiveCode, you don't need to know the driver name to write to. Just
use the command:
open driver "COM2:" for write
This sets the plane for communication. Next, you need to set up the
settings, eg:
set the serialControlString to "BAUD=9600 PARITY=N DATA=8 STOP=1"
These are actually the default settings, so do nothing if these are the
settings you want.
Now you just need to know the commands to send.
https://numato.com/docs/16-channel-usb-relay-module/#the-command-set-20
write "readall" & return to driver "COM2:"
read from driver "COM2:" for 4 -- ie, 4 characters
The read command immediately after the write allows it to accept the
response from the GPIO, in this example, for 4 characters in length (to
receive the 4 hex characters like 16AF)

And that's it pretty much. It's super easy and fun. With Wifi modules you
can use any device to communicate with them. We used iPad mini's which made
it super flexible.

Let us all know if you run into any issues and need help.

All the best
