I'll update this message in a short while with a link to PCB & software files needed to reproduce the board yourself. Think of this as a nice rainy day project!

Very useful document Mark, I hope to take a stab at the CL communication code, with the aim to use MCODE as much as possible - but first I must refresh my rusty grasp of the serial functions so it may take a while..

Many thanks for this interesting contribution and for such a well-done project!
