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 ...

ANSWER: The most obvious difference is size. The parallel port on the back of your computer is a 25-pin port, while the serial port has room for nine pins. But the real difference is in the way they ...

Anyone know? I wanted to get something semi-rugged for a friends CNC setup, or at least something that's easy to get a skin for the keyboard. Thinkpad stuff is ...

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 ...

Easily Add 2 Serial Ports and 1 Parallel Port To Any Computer Add one IEEE 1284 Parallel Port on system Supports 2 x UART Serial Ports All 3 Ports Uses 1 PCI Slot ...

A socket that connects to a serial interface (one bit following another over one line). Serial ports are widely used by sensors for data acquisition, and they were standard on early computers for ...

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.

If you've been using computers for more than a couple of decades, you've probably used a serial port to attach peripherals like your mouse and modem. Until the USB standard rendered them obsolete in ...

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 ...

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 ...
