Hi there
I've got the following problem:
I need to access the serial ports of my PC through an ANSI C program.
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.
Kim
