YOUR MODEM HAS THE ABILITY TO ADJUST ITS IMPEDANCE TO MATCH YOUR
LOCAL PHONE LINE.
From 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.
USING PREFIXES TO FORCE 2400 OR 9600 CONNECTIONS.
Some newer software like Qmodem and Pcplus have a screen in
the dialing directory where you can enter dialing prefixes. In
Qmodem press E and in Pcplus press P to get that screen. Then to
use those prefixes you just put the letter of the prefix before
the telephone number in the directory. (You may have to go to the
Setup and erase the original ATDT).
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) 1
AT&Q6N1DT :negotiates SPEED only 1
AT&Q5S37=11N0DT :*Connect 14400, negotiate Protocol 1 2
AT&Q6S37=11N0DT :*Connect 14400 only 2
AT&Q5S37=9N0DT :*Connect 9600, negotiate Protocol 1
AT&Q6S37=9N0DT :*Connect 9600 only 1
AT&Q5S37=6N0DT :Connect 2400, negotiate Protocol 1
