Appendix D - AT Command Summary
RF300E/RF310E 141
S-Register: S7
Usage: S7=n; S7?
Function: Wait for Connection (Abort Timer)
Unit: 1 second
Range: n=0-255 (0-255 seconds for all switch types except INS64)
n=0-50 (0-50 seconds for INS64 switch type)
Default: 45 (45 seconds)
Description: S7 sets the Abort Timer delay time, which is the length of time the TA waits for a
connection after dialing. If no connection is established during the specified time, the
TA ends the call. The INS64 switch type limits the maximum delay time to 50
seconds or less. All other switch types allow up to 255 seconds of delay.
S-Register: S8
Usage: S8=n; S8?
Function: Pause Time for Comma
Unit: 1 second
Range: n=0-255 (0-255 seconds)
Default: 2 (2 seconds)
Description: S8 sets the length of the pause caused by a comma inserted in a dialing command.
The default setting is 2 seconds, where each unit is one second. S8 may be set for
up to 255 seconds.
S-Register: S10
Usage: S10=n; S10?
Function: DCD Drop Time
Unit: 50 ms
Range: n=0-254 (0-12.75 seconds),
n=255 (do not disconnect)
Default: 20 (1 second)
Description: S10 sets the time after a carrier signal is lost before the TA disconnects. (The &C2
command must be in effect.) The default setting is one second. Maximum delay is
12.75 seconds (S10=254). Set S10 to 255 to cause the TA not to disconnect with
loss of carrier.
S-Register: S25
Usage: S25=n; S25?
Function: DTR Drop Time
Unit: 100 ms
Range: n=0 (50ms),
n=1-255 (100ms-25.5s)
Default: 5 (500ms)
Description: S25 sets the time that DTR must remain low before the TA disconnects. The S25 unit
value for 0 is 50 ms. For values from 1 through 255, the unit value is 100 ms.
S-Register: S29
Usage: S29=n; S29?
Function: On-line Inactivity Timer Period
Unit: 0.25 seconds
Range: n=0—does not disconnect
n=1-255 (0.25-63.75 seconds)
Default: 240 (60 seconds)
Description: S29 sets the on-line inactivity timer period and affects the on-line inactivity timer S30
by adjusting its unit of time. For example, this allows the inactivity of data calls to be
timed down to 0.25 seconds and if no data is received within 0.25 seconds the data
call will disconnect. This is useful for quick connect-disconnects or for continuous
connect-disconnect cycles when combined with the use of Persistent DTR Dialing
(PDD). By default the period is 60 seconds (1 minute).
