S0 – Number of Rings to Auto-Answer
S0 sets the number of the rings required before the modem automatically answers a call.
Setting this parameter to zero disables auto-answer mode.

No automatic call acceptance, acceptance of an incoming call is controlled
by the data terminal (command ATA after RING)

Immediate call acceptance by the terminal adapter (default)

2..n

Call acceptance through the terminal adapter after n “RING ” messages.

Note: The time between two ring messages can be configured using the

IDW-90-configuration command “ringtimer “(default =5 sec.)

S1 – Ring Counter
Ring Counter (read only), S1 is incremented each time the modem detects a ring signal.

S2 – Escape Character
S2 holds the decimal value of the ASCII character used as the escape character.
The default value 43 corresponds to an ASCII '+'..

S3 – Carriage Return Character
S3 sets the command line and result code terminator character. Default: 13 Carriage
Return

S4 – Line Feed Character
S4 sets the character recognised as a line feed. The Line Feed control character is output
after the Carriage Return control character if verbose result codes are used. Default: 10
Line Feed.

S5 – Backspace Character
S5 sets the character recognised as a backspace. The terminal adapter will not recognise
the Backspace character if it is set to a value that is greater than 128 ASCII. This charac-
ter can be used to edit a command line. When the echo command is enabled, the modem
echoes back to the local DTE the Backspace character, an ASCII space character and
second Backspace character; this means a total of three characters are transmitted each
time the modem processes the Backspace character.
Default: 8 (Backspace)

S6 – Dial delay
This S-register defines how many seconds the unit will delay a call attempt.
The timer starts counting after the ATD command has been sent to the adapter.

S7 – Wait time for Carrier
S7 sets the time the terminal adapter will wait for synchronization and also the time the
analogue modem will wait for carrier. Default: 50 sec
