Enhanced parallel ports have been developed, however, to achieve higher speeds — the EPP (Enhanced Parallel Port) achieves speeds of 8 to 16 Mbps. The ECP (Enhanced Capabilities Port), developed by ...

The "serial" part of the serial port's name describes how data is transmitted one bit at a time in a single line or "series." There were also parallel ports on computers that sent multiple bits ...

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 ...

That's why laptops with a true RS232 serial port are at a premium for certain applications.<BR><BR>There are *some* USB-Serial bridges that are better than others.

On the first PCs, the ports were contained on a stand-alone expansion card plugged into the ISA bus. Contrast with parallel port. See serial interface and RS-232. Faster, But Still Serial ...

A parallel port and cable uses eight wires and pins to send eight bits of data -- equalling one byte -- simultaneously. A serial port and cable, on the other hand, sends the data one bit at a time.

Instead the USB to RS232 (serial) converter also pictured above is used as a reset signal. The strobe pin on the parallel port drives an inverter which triggers a thyristor connected to the busy pin.

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 ...
