Seyi,

You have not included the code for the function getc() which leads me to
believe you are using the library getc().
I'm fairly certain the library getc() does not "know" how to poll the RB0 to
receive a character.

I think you have to write a custom routine in place of getc(). It is also
very dangerous to spend that much time (the time required to receive a full
character) inside an interrupt handler. In general you want to get in and
get out, keep your interrupt handlers very short.

Microchip has application notes on implementing software UARTS, this is
actually a FAQ and I'm sure that it turns up in the archive on a regular
basis. I just don't rememeber the AN numbers off the top of my head. A quick
search should turn up two of them.

Good Luck

Wynn
