Torrent description

Virtually every PC has a parallel port that serves as a printer interface. But you can use the parallel port for much more than this, including interfacing to control circuits, data-acquisition devices, and instrumentation. Parallel Port Complete is a complete guide to using and programming the PC's parallel port.

The topics include:
* Basic reading and writing to the original Centronics-type port and PS/2-type bidirectional ports
* How to use the new enhanced (EPP) and extended-capabilities (ECP) modes
* What's in the IEEE-1284 standard for parallel ports
* Port access in Visual Basic under Windows 3.x and Windows 95
* Cable design for faster transmitting and longer links
* How to be sure your program and interface will work with any port
* PC-to-PC communications

With practical examples:
* Simple and latched inputs and outputs
* Expanding the number of inputs and outputs
* Switching power to a load
* Controlling a switch matrix
* Measuring and controlling analog signals
* Triggering periodic actions and events
* Triggering on external events
* Example circuits and programming for Compatibility, Nibble, Byte, EPP, and ECP modes

And Visual Basic program code:
* DLLs to add Inp and Out for port access in Visual Basic
* A form template and port-access routines to provide a quick start to your Visual Basic programs
* Program code for the example circuits
