CSMIM-T1 Hardware Installation Guide 7-9
! (Flash) Inserted between characters in a dial string, causes the
modem to go on hook for 1/2-second and then go back off hook,
as though you depressed the switch-hook button on your
telephone.
; (Return to Command State After Dialing) Added to the end of
a dial string, tells the modem to remain in command state after it
dials the digits preceding the semicolon. This allows you to enter
dial strings longer than 98 characters. After the final Dial
command, the modem tries to establish a connection. To abort
dialing before you attempt to make a connection, type:
ATH<Enter>. Each Dial command except the last one must end
with a semicolon. For example:
ATD 9,5551234; <Enter>.
OK
ATD 5556789 @ 55512345678 W 344 <Enter>.
$ (Bong Detect) Detects an AT&T BELLCORE service prompt to
enter a calling card number and authorization. When the modem
encounters a “$” modifier within a dial string, it waits to receive
this “bong” signal. Once it detects it, the modem continues
processing the dial string. If the time set by register S7 elapses
first, the modem hangs up and displays NO PROMPT TONE.
7.2.1 Operating Mode Dial Modifiers
Use the following dial modifiers to override the \Nn command
setting. Placed anywhere in the dial string, these modifiers cause
the modem to override the \Nn setting for that connection only.
For example, if your modem is set for \N3 (auto-reliable) for
answering and you are calling a modem that you know does not
support error correction, use the Z dial modifier to force normal
mode: ATD 5551234Z <Enter>.
M (Dial in LAPM Mode) Placed anywhere in the dial string, causes
the modem to override current operating mode and dial in LAPM
reliable mode for the current connection only.
Q (Dial in LAPM Mode with Fallback to Normal) Placed
anywhere in the dial string, causes the modem to override current
operating mode and dial in LAPM reliable mode with fallback to
normal mode for the current connection only.
