It used [[programmed I/O]], and thus could present a considerable load on the [[Central Processing Unit|CPU]] when running a high speed line, using [[interrupt]]s. A 64-entry [[First-In First-Out buffer|FIFO buffer]] silo was provided on the input side.
 Both [[EIA RS-232 serial line interface|EIA]] and [[20mA current loop serial line interface|20mA]] physical layers were supported; the EIA model could operate with [[full-duplex]] [[modem]]s. It provided program-set [[baud rate]]s (up to 9600 baud), but not split speed. [[Break]] could be detected or generated on each line.
