S6*
Waiting period for dial tone
Maximum waiting time for the dialling tone. After the modem went off-hook it
waits 7 seconds for the dialling tone (fixed for approval purposes). If it detects a
dialling tone during this waiting period it will start dialling.
If it does not detect a dialling tone, it will check if dial tone recognition is activated
or if the dialling string (Section "
AT
Command Set", command
ATD
) contains the
parameter
W
. If the dialling tone detection is not activated, the modem waits for
the dialling tone.
The value of the S6 register can be between 4 and 7 seconds.
S7*
Waiting period for carrier signal
Wait for the carrier frequency from the other modem. The maximum time for the
modem to wait for a response from the other modem is specified in S7. The time
starts running as soon as the modem has finished dialling. The value of S7 can be
between 0 and 180 seconds.
