Apple II serial cards
:''This article is a sub-page of Apple II peripheral cards.''
Apple II serial cards primarily used the serial RS-232 protocol. They most often were used for communicating with printers, Modems, and less often for computer to computer data transfer. They could be programmed to interface with any number of external devices which were RS-232 compatible. Most serial cards had speed ranges starting from 110 bit/s up to 19,200 bit/s, however some could be modified to go much faster. The most popular and widely used of these cards was Apple Computer's Super Serial Card, a solid design that was often copied for maximum software compatibility of the end product.
== Apple II Communications Card – ''Apple Computer'' ==
The Apple II Communications Card is the original serial card from Apple Computer. Released in 1978 for $225, it was designed to work with modems utilizing acoustic couplers. It offered speeds of 110 and 300 bit/s but with a simple hardware modification (described in the manual accompanying the card) one could change this to 300 and 1200 bit/s, or 1200 and 4800 bit/s. 〔(Apple II History, Chapter 12 - ''Apple II Abroad & Peripherals'' )〕
