Operating a Parallel Device Attached to a Parallel Port
This section describes how a client, in particular, a vendor-supplied function driver for a parallel device, operates a parallel device attached to a parallel port.
The system-supplied bus driver for parallel ports creates a physical device object (PDO) for each parallel device enumerated on a parallel port. The following topics describe how a client operates a parallel device by using the interface provided by the device's PDO:
Opening and Using a Parallel Device
Connecting to a Parallel Device
Obtaining Information about a Parallel Device
Locking and Unlocking a Parallel Port for Use by a Parallel Device
Setting and Clearing a Communication Mode for a Parallel Device
Setting Attributes on a Parallel Device
Reading and Writing a Parallel Device
