The best way for a PIC to communicate with a device over RS 232 is to
use a USART equipped PIC. However, if volume is high and the PIC may be

rtstofer - May 31 2004
If, by 'serin' you mean a serial input to the USART then that would
be on PORT B. If you want to 'bit-bang' a serial input then you can
use any input bit.
