SØ Number of Rings to Auto Answer
(range = Ø-255; Ø = disabled; default = Ø) The number of rings the modem waits for before it auto answers.

S2 Escape Code
(range = Ø-255; default = 43 ``+'') The ASCII value of the escape code. Values greater than 127 cause the escape code to be disabled.

S7 Time to Wait for Carrier
(range = 1-255; default = 50; units = seconds) The maximum time the originating modem waits for a carrier from the remote modem before hanging up, or the time the modem waits when the W dial command modifier is used.

S8 Pause Time for Comma Dial Command Modifier
(range = Ø-255; default = 2; units = seconds) The length of the pause caused by a comma in a dial command (D).

S9 Time to Wait Before Recognizing Carrier
(range = 1-255; default = 12; units = 1/10 seconds) The length of time after a carrier first appears that the modem waits to recognize carrier and turn on DCD. This delay lets your modem ignore spurious signals that are the same frequency as the carrier. Higher S9 values reduce the chance of a false carrier being detected.

S10 Delay from Lost Carrier to Hang Up
(range = 1-255; default = 14; units = 1/10 second) The time your modem waits for a carrier to return before disconnecting. A long enough time allows the remote modem's signal to momentarily disappear without making your modem disconnect. The actual time your modem waits for a lost carrier after it disappears is the difference between S9 and S10. S10=255 causes your modem to act as though a carrier is present, whether one is or not.

S12 Escape Code Guard Time
(range = Ø-255; Ø disables timer; default = 50; units = 1/50 second) The delay required before and after entering the escape code.

S95 Extended Result Codes
(range = Ø - 128 default = Ø) A bit set to 1 in S95 enables the corresponding result code regardless of the W command setting.

Bit ValueDecimal ValueResult Code
01CONNECT XXXX result code indicates DCE speed instead of DTE speed.
12Append/ARQ to CONNECT result code if EC is active.
24Enable CARRIER XXXX result code.
38Enable PROTOCOL XXXX result code.
416Undefined.
532Enable Compression result code.
664Enable TX and RX V.34 CARRIER result code if in asymmetric carrier mode.
7128Enable RINGING result code for ringback detection.

This is a bit-mapped register. To enable or disable a bit, toggle the status with a 0 or a 1. For example, to enable bit 4, issue ATS95.4=1. To disable the bit, issue ATs95.4=0.

Note: Some S-register ranges may be limited due to local PTT-requirements.
