(RPI) A cost-cutting feature of some
modems allowing data
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
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.
