Description

Dial tone delay: The modem performs a dial tone delay before it executes
the next character of the parameter string. The delay length is defined in
the S8 registry.
L
Last number re-dialing.
;
Return to the input mode after dialing. It is added to the end of the dial-
ing string and causes the modem to return to the entry mode when it
reaches “;” (with: message
OK
). This enables the input of
AT
commands
even with a receiver off-hook. The additional
AT
commands can follow in
the same input line after the “;” or they can be transmitted to further in-
put lines. The
ATH
command will abort the connection and the receiver is
hung up.
S=n
Dialing the n-th number from the number pool, which was set up with
the
AT&Z<n>
command.
!
If the character ”!” is a part of the dialing string, the modem will hang up
within the time frame determined in S29 and then goes off-hook again.
^

For PBXs, which connect to the exchange line using the prefix 0 (or 9):
First, blind dialing is activated with :
X3
(see “
ATX3
” command), to be able
to dial a leading 0 without hearing a dialing tone. After 0 has been dialed
via:
D0
, dialing tone recognition can be switched on again using the pa-
rameter:
W
. The modem thus waits for the dialing tone and continues
with the rest of the dial-up (via :12345) only after hearing the dialing
tone. Waiting for the dialing tone may be omitted. In this case, the dialing
command is
ATX3D012345
.
