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 ...

I have been working with computers since the late 70s, and that's not for boasting purposes, but to tell you where I come from. When I started, I was always told to NEVER plug/unplug the following ...

This application note presents the process of converting a serial output into parallel output using common serial-to-parallel register integrated circuits. The document also discussed the CS556x/7x/8x ...

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 the average computer user likely hasn’t given much thought to the lowly serial port in decades, the same can’t be said for the hardware hacker. Cheap serial-to-USB adapters are invaluable for ...

Early microcomputers typically consisted of a half dozen (or more) circuit boards--plugged into a backplane--that implemented the central processor unit (CPU), memory, disk controllers and ...

Getting data to a storage medium requires transmission. Parallel transmission has historically been the preferred way to write data to disk. But at current speeds, serial transmission can be faster ...
