If you want to do this on the PC under Win95 or NT, I can give you tips
on call_external usage under this architecture and on how to access
the serial ports for sending commands to the step motor controllers.
(I am using VC++ 4.2 for the C language part).

If you already have the system device driver for your frame grabber,
you basically need only write a wrapper around the respective calls
to deal with IDL's argc,argv calling conventions.
