- 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.
