IOCTL and Callback Support for Parallel Ports and Devices

This section provides links to topics that describe how the system-supplied parallel drivers support operating parallel ports and devices attached to parallel ports.

Vendor function drivers for parallel devices that are attached to parallel ports are optional. The system-supplied parallel drivers provide extensive support for directly controlling a parallel device as a raw device, and for operating a device's parent parallel port.

For information about the IOCTLs and callbacks that the system-supplied function driver provides to operate a parallel port, see the following topics:

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

For information about the IOCTLs and callbacks that the system-supplied bus driver provides to operate a parallel device that is attached to a parallel port, see the following:

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
