This section describes how a client, in particular, a vendor-supplied function driver for a parallel device, operates a parallel port.
The system-supplied function driver for parallel ports creates a functional device object (FDO) for each parallel port enumerated in the system. The following topics describe how a client operates a parallel port by using the interface provided by the port's FDO:
Creating and Starting a Parallel Port
Opening and Closing a Parallel Port
Obtaining Information About a Parallel Port
Synchronizing the Use of a Parallel Port
Selecting and Deselecting an IEEE 1284 Device Attached to a Parallel Port
Setting and Clearing the Communication Mode on a Parallel Port
Connecting to an IEEE 1284.3 Data Link Device
Connecting an Interrupt Service Routine to a Parallel Port
