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 ...

With the continuing manufacture of new computers, there is a clear and obvious trend of the parallel port becoming less and less common. For our younger readers; the parallel port is an interface ...

The HV509 is a 200V, 16-channel serial to parallel converter. The high voltage outputs and the backplane driver are designed to source and sink ±1.0mA. The high voltage outputs are controlled by a ...

The 74AHC164 and 74AHCT164 are 8-bit serial-in/parallel-out shift registers and are classified as high speed silicon-gate CMOS devices. These devices are pin compatible with Low-power Schottky TTL ...

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 ...

???<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 ...

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 ...

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 ...
