what you should be looking at is an MS-DOS reference manual.  There are
MS-DOS interrupts which return device status information, and you can
perform any interrupt you want by setting up request parameters in a 
Turbo 'regpack' and calling the Turbo routine Intr.  Results are passed
back through the regpack.
