I'm not that familar with Serial communications.  I'm trying to write code
for a pic to communicate RS-485 to other serial devices.  I'm confused on
what the BRGH bit in the TXSTA register does.  I know that it selects between
high and low speed.  But what constitutes high speed 19.2K, 38.4K, etc. what
constitutes low speed 1200 baud, am I just really confused.  Could somebody
please help.
Thanks
