Controlling Serial Ports

[Ste]

I work with serial ports all day. I know all about them from an outsiders
point of view, but I'd like to know all about them from a programmers point
of view. I'd like to make my own very 'very' simple terminal program using
C++ to access the serial ports on a pci card. Eventually I want to send data
out and receive it back in but for now I want to get to grips with what it
takes to open the port(s) and close them.

Can anyone point me in the right direction of some useful material I can
read?

The language sites you posted to are dedicated to the standard C++
language, which knows nothing about hardware or operating system
specific details. You really must ask about this on a forum dedicated
to you operating system and hardware platform. On your way, you might
