S89 Off-line Time
Unit: 1 second
Range: 0, 5-255
Default: 10
S89
sets the length of time, in seconds, a modem waits in the off-line command mode before it goes into
standby mode. If S89 is set to 20 seconds, the modem waits 20 seconds in off-line command mode before
going into standby mode. Setting S89 to zero (0) prevents the modem from ever entering standby mode.
Setting S89 to any value between zero and five (1-4) effectively sets the value to five, because five seconds
is the minimum possible wait time.
Reading and Assigning S-Register Values
Use the S command to assign a value to an S-register and to read an S-register’s current value.
To read an S-register value, in terminal mode, type S, the S-register number, and a question mark (?), and
press ENTER. For example, to display the value of register S7, type ATS7? and press ENTER. The answer will
appear as a three-digit decimal number (e.g.,
045
).
To assign a new value to an S-register, type S, the S-register number, an equals sign (=), and a decimal
number. Convert all ASCII characters to their decimal equivalents before entering them. Valid S-register
decimal values are shown for each register in the previous section. To make the change permanent, use the
&W0 command.
Examples of Assigning Values
1. You want to have longer pauses caused by the comma in a dial command: five seconds instead of
two. Type ATS8=5 to assign 5 as the value for register S8. The modem will now pause five seconds
for every comma in a dial command.
2. You want to configure your modem to answer incoming calls after the fourth ring instead of after the
first ring. To configure register S0
with a value of 4, type ATS0=4 and press ENTER.
3. You are calling long distance to another country code, and it is taking a long time to connect. The
register S7
(time to wait for carrier) factory default setting of 50 seconds is insufficient; a time-out
occurs and cancels the call before a connection is made. To change the S7
value to 75 seconds, type
ATS7=75 and press E
NTER. Now, after dialing, the modem allows 25 more seconds for a carrier
signal before aborting the call. The additional 25 seconds should provide enough time for inter-
national calls.
