There's a very helpful document called "Serial Programming Guide for POSIX Operating Systems" (5th Edition, Michael Sweet http://www.easysw.com/~mike/serial/index.html ).  You have to change the device names to com1, etc., but it works well (at least in Windows NT 4).  I seem to remember having a couple of problems - I think that ioctl() didn't report the right number of bytes in the input buffer, but I could be remembering it wrong.
