I am writing a device driver under OS/2 to talk to a motion 
control board, and I need to be able to flush its input
and output buffers (hardwired memory on the board) on demand.

I can write the routines for strategy calls 7H (flush input) and
BH (flush output), but I don't know what commands my C program
has to issue to get the operating system to issue commands
7H and BH.

If anyone knows what commands to send, or where a list that matches
control program calls to device driver strategy calls can be found
please email me this information.

Thanks,
Chad Schell
