18F2520 HSEROUT baud rate oddity

[Darrel Taylor]

PBP's DEFINE HSER_BAUD is for setting up the baud rate of a USART.
The compiler has no way of knowing when you set BRG16 (BAUDCON.3) in your code for EUSART 16-bit baudrate mode.

For 16-bit mode, you must set the baud rate values manually.

DEFINE HSER_RCSTA 90h ' Enable serial port & continuous receive
DEFINE HSER_TXSTA 24h ' Enable transmit, BRGH = 1
DEFINE HSER_CLROERR 1 ' Clear overflow automatically
DEFINE HSER_SPBRG 64  ' 9600 Baud @ 32MHz, 0.04%
SPBRGH = 3
BAUDCON.3 = 1         ' Enable 16 bit baudrate generator
