[Fernando] wrote in to share his take on building a logic analyzer. He’s using the parallel port to capture data and feed it to the display software of your choice. The method depends on a custom ...

The parallel port is gone as of the time I'm writing this. But its demise was long and drawn-out, even as supposedly better alternatives came along and tried to take its place. Here's how it finally ...

(1) A hardware interface that transfers one or more bytes simultaneously. See parallel interface. (2) A socket on a computer used to connect a printer or other device via a parallel interface (eight ...

First introduced in 1970, parallel ports were originally designed to connect business computers to printers. With their inclusion on the IBM PC in the early 1980s, they became an industry standard.

A port contains a set of signal lines that the CPU uses to send or receive data with other components. Ports are usually used to communicate via modem, printer, keyboard, mouse, etc. In signaling, ...

If your small business is typical, you want to get the longest lifespan possible from your tech investment, and therefore you may have an older dot-matrix or laser printer with a parallel port that ...

If you’ve ever looked into low-level parallel port access you may have learned that it only works with actual parallel port hardware, and not with USB parallel port adapters. But here’s a solution ...

Any peripheral component can be controlled by the 25-pin parallel port by assigning a high & low or ON & OFF state to each pin. During the design of the project, a Super Nintendo Entertainment System ...

The project illustrates how an inexpensive logic analyzer is made to connect with a PC using the parallel port. The project illustrates how an inexpensive logic analyzer is made to connect with a PC ...

I'm moving an old Win95 application over to some new WinXP machines, each with their own parallel port dongle. Software install went well, but I can't get the machines to identify the hardware dongle ...

I have a PC-based DSO that connects via parallel port that I'd like to get working via USB (preferable) or at least ExpressCard. I picked up a USB-parallel adapter from MicroCenter thinking it would ...
