En hurtig Google-søgning fortælller:
| Seriel / com:
| Serial ports work by using a UART chip, a Universal Asynchronous
| Receiver/Transmitter which converts binary signals into signals
| capable of being transmitted. Serial ports are now being outdated
| by newer, faster transfer methods. A standard serial port is
| limited to 115 Kbaud, however some serial card interfaces are able
| to run at up to 460.8 Kbaud.
|
| Lpt:
| There are 3 different versions of parallel ports, Standard
| Parallel Ports, (SPP); which have a theoretical maximum transfer
| speed of 300 Kbytes per second, and Enhanced Parallel Ports, which
| support a theoretical maximum transfer speed of 1.3MBytes/sec. The
| most advanced version is the Enhanced Capability Port (ECP) which
| is usually used for advanced printing devices and supports a
| theoretical 2.7MB/sec.
