If you already have the C routines that access the IO ports
etc, then implementing them as CALL_EXTERNAL, LINKIMAGE or
DLMs (Dynamically Loadable Libraries) isn't all that difficult.
It takes some plundering the first few times to get it right,
but the benefit of being able to do this from within IDL would
make up for it in a short while.

in terms of real time support, I think you're out of luck. I write my IO programs
in C, and then analyze the data in IDL. You can write small C programs that are
callable from the IDL SPAWN command, and also call IDL from windows based programs,
but direct control of the ports is not possible. Too bad, because this would at
least double IDLs usefulness for me.
