Commented:
com2 should be associated to a device, and since devices are just handled like a file, then the normal input/output operations should work in UNIX.

Now, how to do it properly can be found if you get any program in the internet that handles serial communication protocols (kermit for example) and analyze its code.


The OS whose name you are trying to think of is "Linux".

YOu can send data out of the serial port just with
"cat data > /dev/ttyS1"
In un*x, everything is just a file, this includes the serial ports.  Use stty(1) to set the serial port's baud rate etc, appropriately.   If you want to do that in C, see "man termios".
