How do I do that ? I have already tried using fopen("/dev/com2", "r") and fopen("com2", "r") but these only causes a core dump. So how to avoid core dumping and make me able to set the serial port stats (parity, stop bits, bits per byte, serial speed) ? dos.h is not available as far as I can see and therefore inportb() and outportb() as well... The FAQ or the mailing list archive has no response on 'serial' or 'port' which is why I ask here now. Thank you in advance for any answers that might help me clear this up.
