Serial programming in C?

[Duston, Hal]

Bradley,

Not sure what you mean by "accessing the serial port" 
here.  Under Linux (and Unix for that matter), it is 
just another file.  Once the port has been setup, 
(Baud, stop bits, parity, etc.) via either stty 
before starting the program, or ioctl's in the 
program after you open it, "/dev/ttyS0" or whatever 
depending on which port you are using, you can just 
read from it, and capture whatever data is being sent.  
I don't think it is much more complicated than that.  
If I have missed something or you need more help, let 
me know.  There are a few other developers on the list 
as well...
