So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc needs ...

After a youth spent playing with Amigas and getting into all sorts of trouble on the school computer network, I’ve always had a soft spot in my heart for hardware from the 80s and 90s. This extends ...

What is a serial port? Serial ports are generally built into the motherboard. This is why the connectors behind the casing that are connected to the motherboard by a wire cable can be used to connect ...

This converter may help if just the serial port on a personal computer is free, whereas the printer needs a parallel (Centronics) port. It converts a serial 2400 baud signal into a parallel signal.

While doing my usual surfing routine today, I came across an interesting read over at CNET. Some creative artists have made their mark in the oddest of places, a microchip. Some of the designs are ...

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 ...

For PCI bus interfacing, the OX16PC1952 brings together a PCI interface, two high performance serial channels, and a parallel port in one compact, 128-pin TQFP package. This integrated bridge device ...

The Centronics interface is also called Extended Capability Port (ECP) or Enhanced Parallel Port (EPP). This is an interface that simultaneously transfers bits of binary data (sets of 1 and 0) in ...

There was a time when computers had parallel ports. For the hacker types, this meant an eight bit data port, and nine additional pins which could be interfaced with the real world via the 25 pin ...
