When I use Mister E's Pic Multi Calc, it gives me these settings for hser at that baud rate:

DEFINE HSER_RCSTA 90h ' Enable serial port & continuous receive
DEFINE HSER_TXSTA 24h ' Enable transmit, BRGH = 1
DEFINE HSER_SPBRG 77 ' 38400 Baud @ 48MHz, 0.16%
DEFINE HSER_CLROERR 1 ' Clear overflow automatically
