Whoa, you're way out of line here.

First of all, you asked me for a favor.  Second, you don't seem to
understand how email lists work.  I saw you're correction after writing my
post, which may indeed have been after you posted the correction.  That's
how email lists work.  Get used to it and stop whining.

I don't know what signature you are referring to, or what one would have
to do with this issue anyway.  If you'd simply looked, you would have
found the information you want easily.  Most books have this handy little
section called the "Table of Contents".  I'm assuming you meant 16F877, so
the appropriate book is called "PIC16F87x Data Sheet", DS3029C.  After 30
seconds (on a slow day) you would have found the table of contents on page
4.  This shows the section about the USART being section 10 starting on
page 95.  Flipping thru this section you quickly find section 10.1 on page
97 called "USART Baud Rate Generator".  Gee, do you think this just might
give a few clues about the how the buad rate is generated and how to
control it to select your own baud rate?  D'ya think!?

OK, then ask specific questions after you've done your homework.  Your
question made it clear you never even bothered to look at the manual.
That's just plain lazy, then arrogant to ask 2000 people to do the work
you weren't even willing to attempt.

What specifically don't you understand about the baud rate generator?
What do you find confusing on pages 97 and 98?

High level language or not, you'll never be too far from the hardware on
these chips.  Use a high level language if you want, but you have to learn
the architecture else you'll be bumping into mystifying situations
regularly.  In my opinion, the best way to learn the architecture is to do
a few projects in assembler.
