void putchar

putchar('\n') or putchar('\r') both transmit \r\n Just use one or the other. (This makes terminal echo easy)

void sio0_init

(

WORD

baud_rate

)

This function inits sio0 to use T2CON (timer 2) See TRM 14.3.4.1 (Table 14-16) Certain baud rates have too high an error rate to work. All baud rates are .16% except:

12MHZ 24MHZ

• 57600 -6.99%
• 38400 -2.34% -2.34%
• 19200 -2.34%

Possible Baud rates:

• 2400
• 4800
• 9600
• 19200
• 28800
• 38400
• 57600

Any of these rates should work except 57600 at 12mhz. -2.34% is pushing most hardware specs for working. All rates at 48mhz work at .16%
