    S-REGISTER DEFINITIONS S0 - Number of Rings to Auto-Answer S0 sets the number of the rings required before the modem automatically answers a call. Setting this register to zero disables auto-answer mode. Range: 0-255 rings Default: 0 S1 - Ring Counter S1 is incremented each time the modem detects a ring signal on the telephone line.
  • Page 18 SM336 Manual The modem always pauses for a minimum of 2 seconds, even if the value of S6 is less than 2 seconds. Range: 2-255 seconds Default: 2 S7 - Wait Time for Carrier, Silence, or Dial Tone S7 operation is country dependent.
  • Page 19 S12 - Escape Prompt Delay (EPD) S12 defines the maximum period, in fiftieths of a second, allowed between receipt of the last character of the three escape character sequence from the DTE and sending of the OK result code to the DTE. If any characters are detected during this time, the OK will not be sent.
