     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
AT&Q6S37=6N0DT      :Connect 2400 only 1
AT&Q5S37=5N0DT      :Connect 1200, negotiate Protocol 1
AT&Q6S37=5N0DT      :Connect 1200 only 1
AT&Q5S37=1N0DT      :Connect 300, negotiate Protocol 1
AT&Q6S37=1N0DT      :Connect 300 only 1
                     * for all V.32 modems
                     1-for error correcting 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.
