The chip can be programmed with a dongle connected to the parallel port. There are also some print servers that provide interface to parallel port through network. Smaller machines have less room for large parallel port connectors. This is in contrast to a parallel port which communicates multiple bits simultaneously in parallel. A dock was available to connect this drive to a desktop computer's parallel port. It connected to the computer via a parallel port. PicoScope is compatible with Parallel port oscilloscopes and the newer USB oscilloscopes. PicoScope is compatible with parallel port oscilloscopes and the newer USB oscilloscopes. These devices use various interfaces, including RS-232, PC parallel port, and USB. A wide variety of devices were eventually designed to operate on a parallel port. LPT is the designation of a parallel port interface on some computer systems. The L3S was an early portable computer that ran MS-DOS and featured a parallel port. It required a Tandy-1000 compatible printer cable to connect to a standard printer parallel port. The parallel port also uses edge-triggered interrupts. Linux IDE devices can use a "paride" (parallel port IDE) driver.
