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 ...

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 ...

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 ...

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 ...

Serial ports were dropped before parallel ports were - my old R52 has a parallel port but not a serial port. A quick look at that list shows that the last Thinkpads that had the ports were the A31 and ...

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 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 ...

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 ...
