S Registers Definitions S registers generally affect how the AT commands perform. Contents of the registers can be displayed or modified when the modem is in command mode. To display the value of an S register: TYPE: ATSn?, where n is the register number. PRESS: Enter To modify the value of an S register: TYPE: ATSn = r where n is the register number, and r is the new register value. PRESS: Enter S0 Auto Answer Ring Number This register determines the number of rings the modem will count before automatically answering a call. 0 (zero) is that asks modem don’t do automatically answer at all. When disabled, the modem can only answer with an ATA command. Range: 0-255 Default: 0 Units: rings S1 Ring Counter This register, ring counter, is read only. The value of S1 is incremented with each ring. If no rings occur over a 6 second interval, this register is cleared. Range: 0-255 Default: 0 Units: rings S2 AT Escape Character (User Defined) This register determines the ASCII valued used for an escape sequence. The default is the “+” character. The escape sequence allows the modem to exit data mode and enter command mode. Values greater than 127 disable the escape sequence. Range: 0-255 Default: 43 Units: ASCII S3 Command Line Termination Character (User Defined) This register determines the ASCII values as the carriage return character. This character is used to end command lines and result codes. Range: 0-127, ASCII decimal Default: 13 (carriage return) Units: ASCII S4 Response Formatting Character (User Defined) This register determines the ASCII value used as the line feed character. The modem uses a line feed character in command mode when it responds to the computer. Range: 0-127, ASCII decimal Default: 10 (line feed) Units: ASCII S5 Command Line Editing Character (User Defined) This register sets the character recognized as a backspace and pertains to asynchronous only. Range: 0-127, ASCII decimal Default: 8 (backspace) Units: ASCII
S6 Wait Before Dialing This register sets the length of time, in seconds, that the modem must wait (pause) after going off-hook before dialing the first digit. The modem always pauses for a minimum of two seconds, even if the value of S6 is less than two seconds. Waiting for dial tone call progress features (W dial modifier in the dial string) will override the value in register S6. This operation, however, may be affected by some ATX options according to country restrictions. Range: 3-7 Default: 6 Units: seconds S7 Connection Completion Timeout This register sets the time, in seconds, that the modem must wait before hanging up because carrier is not detected. The timer is started when the modem finishes dialing (originate), or goes off-hook (answer). In originate mode, the timer is reset upon detection of an answer tone if allowed by country restriction. The timer also specifies the wait for silence time for the @ dial modifier in seconds. S7 is not associated with the W dial modifier. Range: 1-255 Default: 60 Units: seconds S8 Comma Dial Modifier Time This register sets the time, in seconds, that the modem must pause when it encounters a comma (,) in the dial command string. Range: 1-255 Default: 2 Units: seconds S9 Carrier Detect Response Time Register S9 sets the time the remote modem's carrier signal must be present for the local modem to recognize it. This feature ensures that your modem does not mistake a busy signal, ring, or voice for the carrier signal. The value of this register is in tenths of a second. The default value is 600 ms, although you can change it from 1 to 255. For example, entering a value 13 means that the remote modem's carrier signal must be present for 1.3 seconds for the local modem to recognize it. Setting this value higher increases the chances the modem will not mistakenly identify the carrier signal. Range: 1-255 Default: 6 Units: 0.1 seconds S10 Automatic Disconnect Delay after Carrier Loss This register sets the length of time, in tenths of a second, that the modem waits before hanging up after a loss of carrier. This allows for a temporary carrier loss without causing the local modem to disconnect. The actual interval the modem waits before disconnecting is the value in register S10. Range: 1-255 Default: 14 Units: 0.1 seconds S11 DTMF Dialing Speed This register determines the dialing speed which is prefixed for each country. Range: 50-255 Default: 95 Units: 0.001 seconds S12 Escape Guard Time This register sets the value (in 20 ms increments) for the required pause after the escape sequence (default 1 s). Range: 0-255 Default: 50 Units: 0.02 seconds S13 Pulse Dialing Control This register determines pulse dialing is disabled or enabled. ATS13=0 Disable Pulse Dialing ATS13=1 Enable Pulse Dialing Range: 0-1 S14 Bit-mapped Register Bit-mapped register S14 lets you control modem echo, responses, dialing method, and the original or answer mode.

In this mode, the values for this register are 0 to 255 in hundredths of a second, and the default value is 0.05 seconds. If you will be entering synchronous mode after dialing asynchronously, this register determines how long the modem waits before looking for the Data Terminal Ready signal. This lets you detach the asynchronous terminal and connect a synchronous terminal while remaining in the Data Mode. The default value is 5. Range: 0-255 Default: 5 Units: 0.01 seconds S26 Request To Send-to-Clear To Send Delay This register affects synchronous operation only and applies only when you are using the &R0 command. This register determines how long the modem waits to turn on the Clear To Send signal after a Request To Send OFF-to-ON transition in 10 ms increment. The default value is 1. Range: 0-255 Default: 1 Units: 0.01 seconds S29 Bit Value Function 0-4 Mapping to AT*I 5-7 Mapping to AT&U S30 Inactivity Timer S30 specifies the length of time (in minutes) that the modem will wait before disconnecting when no data is sent or received. This function is only applicable to buffer mode. Range: 0-255 Default: 0 (Disable) Units: minutes S45 Timer to Control Sleep Mode This command displays the number of seconds of inactivity (no characters sent from the DTE, no RING) in the off-line command state before the modem places itself into standby mode. A value of zero prevents standby mode. Note: If a number between 1 and 4 is entered for this register, it will set the value to 5, and the inactivity before standby will be 5 s. This is done for compatibility with previous products which allowed time-outs down to 1 s.
