To answer the above question, no it wasn't the issue :)
I have found that after making certain that the postscaler was set at 1:1 I
do have
communications although it is garbage characters. I have verified the RS-232
circuitry external to the PIC (MAX233) by tying the logic level RS-232 RX
and TX
together and watching the echo on my terminal software...all is fine there.
I have verified that all registers associated with asynch communications and
the SPBRG value
are properly set for the 8MHz INTOSC.
I wonder if the OSCTUNE value is out of calibration? I'll have to borrow a
frequency counter
and verify the internal oscillator. Going to try a canned stable clock
source in the next day
or two and see how that works. BTW, I can throw a 16F628 using INTOSC on
this MAX233 and
communicate fine all day long!
Thanks for all the help and I'll post the results of my tests.

Regards,
Stephen D. Barnes
