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.
