Subject: Serial port programming
Date: Sun, 22 Aug 1999 23:32:00 -0000	[thread overview]
Message-ID: <37C0EAC4.63151D86@tbit.dk> (raw)

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
