Serial I/O

["saxyg2004@gmail.com" <saxyg2004@gmail.com>]

I was wondering how I would set up a program that would allow a
computer to send information through a serial port.  When the open or
create command and reference the serial port I get a name error while
compileing.  I am guessing that this is caused by me not initializing
the port. How would I be able to initilize the serial ports, or what
functions would i have to use?

thanks
