Hi C. BRGH is just to select FOSC / ( 16 x [baud+1]) or FOSC / ( 64 x [baud+1]) in 8 bit asynchronous mode.
One thing I need to tell you.. As your serial is up the swanny without a paddle. Have to checked BRGH16 to make sure it is zero? That puts the transmission / receive into 16bit mode.
Also.. SPBRGH and SPBRG make a 16 bit divisor for values on the table above 255 in 16bit mode. It isn't needed for 8 bit BUT!! (and I have a big butt), SPBRGH must be 0.
