     Procomm  Plus 2.0 has bugs. PCP 1.xx is OK as is PCP 2.01  or  higher.
The Init string for PCP is AT&F&C1&D2^M (add s36=7 before the ^M for  Turbo
and  'white' V42bis modems)- CTS/RTS=ON   Autobaud detect = OFF - drop  DTR
to  hangup = YES - modem speed 38,400, (19,200 or 57,600) - set 'send  init
if  CD High' = YES  - To get to the screens to set these parameters,  press
<Alt>S.  You must goto setup if you use an alternate IRQ and set  the  IRQ
for that comport.

    (Non-RPI)  Pcplus  intercepts all progress messages,  unless  you  dial
(ADTDxxxx) in Terminal mode so you don't need S95=44 or 45. If you want  to
see  modem-modem  connect speed, use s95=1 (default s95=0  shows  computer-
modem speed).

     If  the  Procomm includes ATZ in it's init, type  AT&F&W  in  terminal
mode, then go back and change it to the setting in the 1st paragraph.

     In  the dialing directory (PCPlus for Dos) press P and you  can  enter
any of the following......

AT&Q5N1DT           :negotiates SPEED and Protocol (default- non RPI)
AT&Q6N1DT           :negotiates SPEED only  (default RPI)
AT&Q5S37=11N0DT     :*Connect 14400, negotiate Protocol 2
AT&Q6S37=11N0DT     :*Connect 14400 only 2
AT&Q5S37=9N0DT      :*Connect 9600, negotiate Protocol
AT&Q6S37=9N0DT      :*Connect 9600 only
AT&Q5S37=6N0DT      :Connect 2400, negotiate Protocol
AT&Q6S37=6N0DT      :Connect 2400 only
AT&Q6S37=5N0DT      :Connect 1200 only
AT&Q6S37=1N0DT      :Connect 300 only
                 * for all V.32 modems     2-for V.32bis modems
NOTE 1: The above strings are using buffering which allows the computer  to
have  a higher speed than the modem. If you still have trouble try  &Q0  in
place of &Q6 and set your computer speed the same as the modem speed.

NOTE  2: I discovered when a user couldn't connect to a 300bps modem,  that
if  I  did AT&F (set &C0&D0) before using the dial prefix,  then  it  would
connect. This is worth a try on stubborn 1200bps modems too.

NOTE 3: If none of these work, fax me the number and I will test it to  see
if I can get a connect, and at what speed.

NOTE  4: The new LC (Low Current) modems use the command Fx (F1 F2 etc)  to
set modem speed. Replace the S37=xNx commands above with the Fx. (see  your
manual for speed for each Fx command). Command would be AT&QxFxDT

NOTE:  5  If  you  try to force a speed higher than  the  other  modem  can
connect,  you  will get NO CARRIER. Set your modem speed  to  the  software
speed  just above the modem's highest speed (14,400 set 19,200 - VFast  set
38,400) and let the modem negotiate whenever possible.

NOTE: 6  RPI modems cannot use &Q5
