I have a starting project that is going to be basically a front panel processor
It will talk to the PC via rs232 (possibly using the USART) and to a gps module
using serial CMOS. I am not hurting for pins and I am thinking of bitbanging the
gps communications and _possibly_ the PC too. The gps will run at 9600 baud, the
pc I haven't decided, but I am thinking 19200 (there is a lot more data on that
line)

The main question I have is, the PIC documentation has lots of tables giving
crystal speeds and some form of constant (I don't have the book in front of me)
that gives a baudrate with a bit of error, the errors vary from 0% to several
percent. How much can I get away with? I'd like to run the PIC as fast as
possible as it is also going to be controlling a VFD and some buttons.

Thanks

Anthony
