S-Register
Description
S6=
n
BLIND DIAL PAUSE TIME
This S-Register determines how long (in seconds) the
modem waits, after going off-hook, before dialing a
telephone number when Dial Tone Detect has been disabled
(X0, X1, or X3). The dial modifier W causes the modem to
ignore the contents of this register. Result code types X2
and X4 enable dial-tone detection, and therefore do not use
this register.
n = 2–255 (seconds).
Factory setting is 2 seconds.
If a value less than 2 is entered, the default value (2) will be
used.
S7=
n
NO ANSWER TIME-OUT
This S-Register determines how long (in seconds) an
originating modem waits before abandoning a call when no
answer tone is received. This register is not associated with
the W dial modifier.
n = 1–255 (seconds).
Factory setting is 60 seconds.
S8=
n
“,” PAUSE TIME DIAL MODIFIER
This S-Register determines how long (in seconds) the
modem pauses when it encounters a comma (,) in the Dial
command string.
n = 0–255 (seconds).
Factory setting is 2 seconds.
S10=
n
NO CARRIER DISCONNECT TIMER
This S-Register determines how long (in tenths of seconds)
the modem allows the carrier signal to be off before
disconnecting the call. This allows for a temporary loss of
the remote modem carrier without causing the local modem
to hang up. When set to 255, the modem functions as if
carrier is always present and therefore will not disconnect
upon loss of the remote modem carrier.
n = 1–255 (1/10 of a second).
A value of 255 disables the timer.
Factory setting is 14 (1.4 seconds).
