YOUR MODEM HAS THE ABILITY TO ADJUST ITS IMPEDANCE TO MATCH YOUR LOCAL
PHONE LINE.
                          Enter  'terminal' mode. Type AT\E1 and press  the
[enter]  key. This tells your modem to adjust to your phone line  when  you
make  your  next  V.32bis call. Make the V.32bis  call  immediately   after
entering AT\E1. You may not connect on the first  try, as the modem will be
making  this  adjustment. However your modem will now be  adjusted  to  the
phone  line, and this step will not have to be repeated unless  you  change
phone lines.

              Normal INIT for modems on a PC AT&F&C1&D2
     Sometimes, even though the modem seems to get a good connect  (usually
with  hi-speed modem) it does not actually make the  connection  correctly.
(It  may  be the OTHER end making the error). Often if you use one  of  the
(prefix)  strings to force that connect speed the connection will  be  made
'solid' on both ends.

                 V.32 / V.42bis Dialing Prefixes

     The  normal dial Prefix is ATDT. If the number  is  423-1563 then   it
sends ATDT4231563 to the modem, which then  dials,   and connects. This  is
using  auto-speed  (baud)  negotiation as well   as  negotiating   Protocol
(V.42bis, MNP etc.). Some modems/software you  will call do NOT like  this.
Listed are alternate dial Prefixes you may use.

AT&Q5N1DT           :negotiates SPEED and Protocol (default)
AT&Q6N1DT           :negotiates SPEED only
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

              Connect result messages / modem speed

S95=44   gives  you full result messages with CONNECT  (modem  to  computer
speed).  If  you need CONNECT (modem to  modem) speed the same  as  CARRIER
(modem  to modem) use S95=45. When running a BBS, try  S95=3 and  you  will
get only CONNECT(carrier) message, with \ARQ for error correcting   modems.
Always  set  your  'speed'  in your program  to   the  highest  permissable
computer  -  to - modem speed (check your manual). The  V.32xx  or  V.42bis
modem will take care of modem to modem speed.
