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.
