Hello,
   I am using pic16f877 to communicate asynchronously
with the PC.
The pic transmit to the PC operates with no problem,
with or without interrupts.

To receive from the PC, I have used interrupt enable
and follow the directions given in microchip manual
for setting flags, etc. However, whenever I check
RCIF, it has never been set to indicate the reception
of a byte.
If I try to read the RCREG I get empty (which it
should ). SOmehow, my receiver is dead. I have tried
several chips, same problem.

However, if I use the Pic Basic compiler, I can read
the keyboard entry with no problem. Same hardware.
Same ports.

I have read the manual umpteen number of times but
don't see what could be wrong.
I would appreciate any help on this matter.

Thanks.
Mike.

P.S. Is it possible there have been revisions to the
pins or ?? in chip?

Thanks.
