(Ok, so I overstated the problem - no global nuclear meltdown, it just
causes me headaches ;-)  Sorry about my warped sense of humor for subject
lines. )

I'm using the CCS compiler to send an RS232 signal out a pin to a PC.  I
converted this code from a Microengineering Labs PICBASIC program, which
seems to operate OK in my test circuit (thus eliminatting the test circuit
from consideration - I hope!)  BTW, I was impressed with the code compaction
of CCS C vs. ML Basic.  CCS is not really so bad!

The PIC (a 12C509) hooks up to a PC serial port through pin 2 and ground.
The BASIC routine has an option to invert the signal, so it works right with
the voltage levels in a PC serial port (or close enough).  I'm using an
equivalernt in the CCS compiler I think.

I clamp a 12C509 into the (previously working) zif socket, and get zippo for
output.

Even a simple program:


#USE RS232(BAUD=2400, XMIT=PIN_B2, RCV=PIN_B3, INVERT, PARITY=N)

#USE FAST_IO

main:

    SET_TRIS_B(0B11111011);

    printf ("Hello cruel world");

goto main;


Doesn't show up on my PC.

Can we all sing "Oh Where is my Breakout Box" with me?

Later today I'll have a chance to put a scope on it and see if ANYTHING is
coming out.  Anybody got any suggestions?  What about the FAST_IO statement?
