    Oh yeah.  Yeah.  I am using a cable from one computer to the other, and 
trying to use it just like a serial cable, to send and receive data from one 
computer to the other.  I know there are other programs such as LapLink and 
o
on, to do this, but i want to do other things within my program aswell.  Soo. 
Yeah, all i basically want is some example source to just send a letter, say 
the letter W, through the serial port, and be able to input it at the other 
end, and print it to the screen.  Anyway, thanx for this example source 
e..
