No joy with serin2

Use DEBUG/DEBUGIN, see if it works better.

I'm not a fan of the internal OSC for serial comm... yes some use it and have no problem with.. i know.... i know...

Use 8MHz internal, then test it with 4MHz internal... maybe, maybe maybe. Last resort, fine tune the internal OSC with OSCTUNE register

Well, finally I've got this thing working. I got suspicious of Microchip's prototype board and just breadboarded the whole thing, and it worked perfectly.

I think I will go with an external ceramic oscillator for the final circuit, for the sake of reliability. If I hook up a 20mhz oscillator, all I need to do is set @ device EXTRC_OSC_NOCLKOUT, define OSC 20, and get rid of the OSCCON completely, right?

For the config with 20 mhz external.

Yes

DEFINE OSC 20

Thanks, I appreciate the help.
