i'm currently trying to read and write a stream of either integers or chars into a device plugged in a serial port.
i know that linux has a device for it under /dev

i tried using the standard open() to open that device but it doesn't seem to be doing anything.
my question is, how do you communicate with a serial port?

any snippet will be of great help,

thanks in advance, i really appreciate any help

The best source of information is the "Serial Programming HOWTO" (e.g. at http://en.tldp.org/HOWTO/Serial-Programming-HOWTO/)

The serial port test program you can find at http://www.comptechdoc.org/os/linux/programming/c/linux_pgcserial.html demonstrates how to use the serial port.
