MODEM S-REGISTERS
The value of an S-register is modified by ATSn = x, where
n is the register number and x is the value to be stored in
that particular register. Each S-register has three values that
may be configured for different countries: a default value,
an upper limit, and a lower limit. The values shown in this
manual are for North America.

Description
Sets number of rings to auto-answer. The country configuration may disable the modem’s
ability to detect a telephone line ring signal. In this case, the modem will never
automatically answer the telephone regardless of the S0 setting. Default = 0 (auto-answer
disabled)
Returns the number of times the phone rings. Default = 0
Sets Escape Sequence Character. Setting S2 to a value greater than 127 disables the
character escape sequence, preventing the modem from returning to Command state
when in the On-Line state. Default = 43
Sets the End of Line character. Default = 13
Sets the Line Feed Character. Default = 10
Sets the BackSpace Character. Default = 8
Delays to Wait Before Performing a Blind Dial. Default = 2 seconds
Delays to Wait for Carrier after dialing. Default = 30 seconds
Delays to Wait when a Comma Dial Modifier is Processed. Default = 2 sec.
Time Carrier Must be Present Before Being Recognized. Default = 0.6 sec.
Delay Between Lost Carrier and Hang Up. Setting S-register S10 to 255 prevents the
modem hanging up the telephone line because of a loss of carrier. Default = 14 tenths of a
second
Multi-Frequency Tone duration. Default = 95 milliseconds
Escapes Prompt delay time. This is the prompt delay time for escape sequences from the
On-Line state to the Command state. Default = 50 fiftieths of a second
