INT 15h,  82h (130)      Device Program Termination                      many

Provides an interface to discontinue the use of a device by all
processes currently using the device.

On entry:      AH         82h
BX         Device ID

Returns:       Carry      Set if service not supported, else cleared

                                                                          

Notes:         The PC, PCjr, and the XT dated 11/08/82 do not
support this service.

This interface is supported for multi-tasking
environments, where more than one process (or task)
may be executing in the system. Usually the
operating system will supply the handler for this
service; this way, the operating system can keep
track of which process is using each device on the
system.

The operating system will use this service to
discontinue the use of a device by all processes
currently using the device.
