Thanks very much....I'll try that on my xmtr end of things. I didn't realize the pic drew such little current in the sleep state.

That sounds like it may well solve the problem although searching this forum I also ran across some posts on SERIN and TIMEOUT.

I guess the TIMEOUT will react to ANY change in pin state, noise or otherwise? So it's a good idea to use a pulldown on the SERIN pin? I don't see anything but a steady low when my panasonic ired receiver isn't receiving.....no noise, so I didn't bother.

I was wondering if, in my code, I'm using TIMEOUT correctly and I'd like to understand it better.


SERIN PORTA.0,T1200,50,NONE,[QUALA,QUALB],DAT

(1) Does it then wait 50ms wait for a pin state change and go to NONE

or

(2) Does it wait 50ms for a pin state change, look for the qualifiers and then go to NONE? (if the qualifiers aren't there).

Or is all this about a toggle on the pin nonsense and it looks for legit RS232?

Thanks again for the help.
