Your problem is the internal oscillator. As already suggested in post#4, use a 4 MHz xtal or a resonator also for the pic, and you will see that the serial communication will work.

Might not be the internal osc though...Originally Posted by aratti
As has been pointed out somewhere (don't remember where) before, those internal oscillators aren't as loose as they used to be...unless of course it's an older chip in the first place.

The schematic for the EDE702 uses a ceramic resonator, but your code comment suggests you are using a crystal.
Did you add two 22-27pF capacitors on the crystal?

Hi,
1. Tried BAUD CON 6 (instead of 2)..... no go
2. The crystal on the EDE702 has two 22pF caps going to ground
3. Haven't tried a crystal for the Pic (sender) but it's a '628A
Will make the correct schematic and post it (right now I don't have access to a drawing program that will do schematics). Maybe I'll get access to Orcad tomorrow.
I start to get a feeling that the EDE702 is just dead
Till then thanks for your suggestions,
Tom

That's what I said to try in post 4.
