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
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.
