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.

My X31 had a parallel port, and there was a serial port on the optional UltraBase. I've never seen the UltraBase in person, but I expect it makes the X31 one thick but tiny footprint beast. I ...

Back to the 1970s Centronics Data Computer Corporation introduced a parallel port for printers in the 1970s. It was adapted for the IBM PC in 1981 and standardized by the IEEE in 1994 (see IEEE 1284).

For our younger readers; the parallel port is an interface standard used for bi-directional communication between a computer and a variety of peripherals. The parallel port’s demise is partially ...

QWhen I connect my printer through a parallel-port Iomega Zip drive, I get too many overrun messages from that HP 4. AThe signals coursing through the parallel-port cable are bumping into each ...

The first two-way parallel ports allowed for speeds of 2.4Mb/s. Enhanced parallel ports have been developed, however, to achieve higher speeds — the EPP (Enhanced Parallel Port) achieves speeds of 8 ...

An IEEE standard for an enhanced parallel interface (parallel port) for personal computers, superseding the Centronics interface. Introduced in 1994, IEEE 1284 can send addresses, allowing ...

It’s a sound card for the parallel port that isn’t just a resistor DAC like the Covox Speech Thing. The design of the OPL2LPT is pretty much what you would expect; it’s an OPL2 chip, opamp ...

Parallel- and serial-type phone systems are not directly related to parallel and serial computer ports. A parallel port and cable uses eight wires and pins to send eight bits of data -- equalling ...

Most old printers connect using a parallel port on the computer. New printers can connect using a USB port, a network adapter built into the printer or, most recently, the wireless printer adapter.
