You can drive the signal line from the power supply in a pull-up fashion.. 
cause the PIC UART doesn't drive the line directly.. It only sinks, not 
source current... 

It just needs a diode, and it uses only 1 wire for comms.. which is a drawback 
with a fixed DC voltage on that line during "idle" times... So, i don't know 
if there are advantages over RS485...

cheers..
