I was looking into the PIC calculator. I would like to incorporate USART into the code as advised.
I have got few statements from the PIC calculator which are:

Code:
DEFINE HSER_RCSTA 90h ' Enable serial port & continuous receive
DEFINE HSER_TXSTA 20h ' Enable transmit, BRGH = 0
DEFINE HSER_SPBRG 12  ' 4800 Baud @ 4MHz, 0.17%
DEFINE HSER_CLROERR 1 ' Clear overflow automatically
and also
Code:
RCSTA = $90 ' Enable serial port & continuous receive
TXSTA = $20 ' Enable transmit, BRGH = 0
SPBRG = 12  ' 4800 Baud @ 4MHz, 0.17%
I would like to ask, if these are the only statements which I need to put in the code and then replace DEBUG with HSERIN & HSEROUT and also use my simple RF modules on TX & RX pins of my PIC instead of the ones I am using now?
I mean would these statements be correct?
Code:
HSEROUT "MT3",code,"S" & HSERIN [WAIT("MT3"),code,STR string\1\10]
Also Dave, to answer your question -
If you are using radio modules like the ones found at rentron.com then they need to be "trained" to receive data.
. I am using simple RF modules and not any special kind.
