I have had no luck whatsoever in getting any action out of the new Parallax transceivers (part # 27982).
Attached is the SXB code I have been using to test the parts. Two transceivers are on the same PDB board.
One sends out 4 'U's, then a '!' then a 'A'. The second transceiver is then quered to see if there is a '!' on board and if so it looks for an 'A'. These two characters are never found.
I have no idea about how to proceed from here. Any ideas out there?
