I am working on a device that will have a pic
listening on a serial line and waiting quietly until a
special character sequence is sent on the line, I then
want the pic to switch the 232 line to an alternate
serial line. At first I thought I'd just take the 9600
coms in from the source and output it to one set of
output pins, then once the key sequence is detected
divert the output to an alternate serial port.
However I think I could use a smaller PIC and simply
have the chip drive a SS relay to switch between
destination serial ports. This is a PC to PC serial
link.

Am I off base or can I use some SS relays to switch to
different output ports?
