Hello all,
    How does DJGPP handle serial port access?  Specifically, how can I
open a COM port?  I need to use the open() function, and I've tried
COM1, /dev/com1/, /dev/tty00, /dev/ttyS0, and /dev/cua0--none of them
work.
    I need to use open() because my code uses tcgetattr(), tcsetattr(),
and select().
    I've looked at bcsio, but I'd like to be able to compile my Unix
code as-is, if possible.  I'm in the process of looking at dzcomm.  I'm
also searching through the old posts, but so far I haven't found
anything promising.

Thanks for any input,
Dan
