Hi skimask
Thanks for the reply.

The data has been sent using the Serial Communicator window in MCS. Have been testing using single characters and all three at a time. Trying to just get a framework to start from.
The end app is going to be PIC -> PIC in a master/slave config so the scheme has to be a bit more bulletproof than this. There is one controller and needs to be a significant number of slaves (sort of an Egypt/pyramid kind of thing in case Mel happenings by).

I'll be trying your suggestions and exploring it more this morning.
Thanks again

Bo
