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 ...

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 ...

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 ...

This article is the 3rd part of the series MCU Programming Basics, which is communication with external peripherals using serial communication. It differentiates the difference between parallel and ...

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.

???<BR><BR>I have a propriatery RS232 device that I need to connect to a computer that has no serial ports (newer laptop). The hardware has a dongle incorporated into the cable to unlock the software ...

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 ...

The circuit shown in Figure 1 provides a simple, low-power means of digitizing analog signals and sending the data directly to a PC's serial port where it can easily be read, analyzed, and stored. The ...

Device drivers are the programs that enable computers to communicate with installed hardware such as scanners. When a computer does not recognize an otherwise functioning scanner that is connected to ...
