     RPI= Rockwell Protocol Interface. (for the AFC/X,AMC/X,Pocket modems).
There is a V42bis.DRV file on the diskette, and the Software must recognise
RPI  for it to Interface that with the modem. Any software  that  reconises
RPI will have a driver included. RPI based modems do not use RTS/CTS of the
program, it too is RPI controlled. Always set modem speed to 2400.

     If you are having trouble, then in any program that does use RPI, just
set  the entry of the phone directory to NONE (not to MNP/V42) to turn  off
protocol.

     If  the program does not support RPI, do NOT set RTS/CTS flow  or  any
MNP  or  V42(bis) options. It will only work as a plain 2400  modem  (Hayes
2400).

     There are not very many term programs that suport  RPI for
V42bis. Right now I know of 3. (in order of ease of use).

     NOTE:  If you need modem-based V42bis (mnp) the cheapest  Zoom  modems
w/V42bis are the FCV/FXV (FC9624V FX9624V). They are often available  below
$150 at retail or mail order.
