Hi, Peter
I did some measurements on the intOscs ( not '819 ...)
16F84 ... +/- 20% is to consider for the EXT RC osc ... ( includes components tolerance )
16F628(A) ... +/- 10 % of nominal freq is to consider
16F88 ... +/- 2 to 3 % of nominal freq to consider.
But you have the "OscTune" register to play with ... The use of MPLAB + ICD2 could be helpful here !!!

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

Can you try to use 2400 for DEBUG_BAUD. I'm using other PIC, and it is working fine with internal OSC.

For what it is worth, I have never been able to use the internal reliably to serial. It may work on the test bench some, but move it someplace else (different temperature ?) and it will start sending "junk".
At least if you use a crystal with built in caps (resonator) it can be pretty much placed anywhere on the PCB with jumpers and super glue

Thanks folks.
No, the speed must be 600 'cos that's what the receiving device wants. I will probably end up using a resonator, just 'cos I can!
