Use Hercules to send some text in Serial tab mode, and if it receives it, all is fine with the Jaycar cable and you can move on to the next bit. It does sound like this cable is working.

I dug up a matching DB-9 connector in one of my ancient spares boxes
and did this test on the Jaycar cable. Your intuition has been proven right
redbeard, I think. Just to be sure can you check the snapshot attached of my Hercules outputs. Does text appearing twice and in different colours mean its working? As you can see I couldn't get it to respond to CR/LF hex codes, but maybe this doesn't matter.
Meanwhile I'll try and extend the loopback test to include the Meade serial cable (#505 from memory)
