Hey guys

Talking about the handshake lines in (RTS CTS DTR, do u have to program
the pic (example: pic16c73 in this case) to configure these lines, even
when you're not going to use it? What I'm saying is that I'll fixing up
a null modem for the RS232 cable, using only TX, RX & gnd.

Take the example below quoted from a tutorial application from
microchip,

It says, "We will also use RC5 and RA5 as the terminal handshake lines
RTS and CTS, although these signals are not used in this application.
Following convention though we will set RTS as an input and CTS will be
driven low. "

the codes:" ;RTS must be = 00 cts MUST = 00
             BSF PORTC,5 ;RTS
             BSF PORTA,5 ;CTS

Dazed & confused?
Bye
