For portable-sensing and data- acquisition applications, a laptop computer and its parallel port (LPT) make good bedfellows. Yet in the effort to extend battery life, many microprocessors and entire ...

A parallel port, which is standard equipment on nearly every IBM-compatible PC, can be connected directly to TTL/CMOS circuits. The standard parallel port provides 12 logic outputs and five inputs.

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 ...

Many laser printers last for years, so businesses often keep older laser printers around even after upgrading other hardware. Many older laser printers use a parallel port interface rather than the ...

STMicroelectronics (headquartered in Geneva, Switzerland) is promoting eveloped a pair of low-voltage, high-speed transceiver ICs that conform to the IEEE1284 bi-directional parallel port interface ...

In the olden days, plugging something into your computer—a mouse, a printer, a hard drive—required a zoo of cables. Maybe you needed a PS/2 connector or a serial port, the Apple Desktop Bus, or a DIN ...

Right now DAGU is in the prototype stage, but already there are some really interesting features: the interface allows for a basic preview of the job before it begins, and should be somewhat ...

In computing, a bus is defined as a set of physical connections (for example, cables, printed circuits, etc.) that multiple hardware components can share in order to communicate with one another. The ...
