Rockwell Protocol Interface
(RPI) A cost-cutting feature of some modems allowing data compression and error
correction (e.g. ITU-T V.42bis, V.42) to be provided in software instead of
hardware.
Usually an RPI modem comes with RPI-aware software (e.g. the low-end RPI models
of Supra come with the COMit which supports RPI, providing MNP 2,4,5,7, V.42 and
V.42bis). RPI is not supported by many commercial packages nor by current
releases of popular shareware communication programs (Telix v3.22 and Telemate
v4.12). ProComm Plus for Windows 2.0 will support RPI.
Currently Rockwell produce two classes of RPI chip set. The original is capable
of 2400 bit/s data, 9600 bit/s class 1-only fax. The newer one is capable of
14400 bit/s data/fax. Currently there are no RPI chipset from Rockwell
supporting speeds higher than 14400 bit/s.
