AT commands
Digi TransPort User Guide 133
S0 V.120 Answer Enabled
Units: Rings
Default: 0
Range: 0-255
S0 is used only in V.120 mode to enable or disable automatic answering of incoming ISDN calls.
Auto answering is disabled when S0 is set to the default value of 0. Setting S0 to a non-zero value
enables auto-answering.
The actual value stored determines the number of “rings” that the router will wait before
answering. For example, the command ATS0=2 enables auto-answering after two incoming rings
have been detected.
With each ring the RING result code is issued and the value stored in
S1 is incremented. When the
value in S1 equals the value in S0 the call is answered.
S1 Ring count
Units: Rings
Default: n/a
Range: n/a
When ADAPT detects an incoming ISDN call on an ASY port, it will print
RING to the ASY port at 2
second intervals. It also increments the S1 register, counting how many times RING is printed.
S2 Escape Character
Units: ASCII
Default: 43
Range: 0-255
The value stored in
S2 defines which ASCII character is used as the Escape character, which by
default is the + symbol. Entering this character three times followed by a delay of 1-2 seconds
and then an AT command will cause the router to switch from on-line mode to command mode.
S12 Escape Delay
Units: ms
Default: 50
Range: 0-255
The value stored in
S12 defines the delay between sending the escape sequence and entering an
AT command for the router to switch from on-line mode to command mode.
