S-Register 8—Pause Time for Pause Delay Dial Modifiers
This S-Register determines how many seconds the modem pauses while dialing
when it encounters a K, k, “,”, or < dial modifier. Pause Delay (AT
*
DP) must be set
to S8 (AT
*
DP4) to use S-Register 8’s setting.
This S-Register also determines the time duration of the pause delay for the “,”
character when used in an AT command string. The modem pauses for the specified
time before continuing to process the command string.
With the “,” k, K, or < dial modifier, if S-Register 8 is set to 0 or 1, the pause delay
defaults to two seconds.
S-Register 10—Carrier Loss Hang Up Delay
S-Register 10 determines how long, in 100 millisecond increments, data carrier must
be lost before the modem hangs up. NOTE: This applies to V.22bis, B212, V.21, and
B103 operation only. To use S-Register 10’s setting, the front panel DCD Loss Dis
option (AT
*
CD) must be set to S10. Also, if S-Register 10 is set to 255, the modem
will not hang up because of a carrier loss.
Setting the AT
*
CD (DCD Loss Disconnect option under the TERMINAL OPT’S
menu) to S10 enables the DCE disconnect feature, for V.32, V.32bis, and V.34
modulation modes. For these modes, the S-Register 10 determines the length of time,
in seconds, for the modem to disconnect when the remote modem goes on hook
without sending a longspace or PSTN cleardown.
In Normal or Direct modes, S10 must be set between 1–9 seconds. For Reliable
mode, S10 must be set between 1–8 seconds. These selections result in Disconnect in
the specified time after the modem leaves data mode and starts to retrain. Values of
S10 other than the ones specified above disable the DCE Disconnect feature.
