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.
0No automatic call acceptance, acceptance of an incoming call is controlled
by the data terminal (command ATA after RING)
1
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
ID-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 character
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 a
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
