Digi TransPort WR Routers User Guide 128
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 the Escape character. By default, the escape
character is the + symbol. Entering this character three times followed by a delay of 1-2 seconds and
then an AT command causes 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.
S15 Data Forwarding Timer
Units: 10ms
Default: 0
Range: 0-255
S15 sets the data forwarding timer for the ASY port in multiples of 10ms. The default data
forwarding time is 20ms. Normally, there is no need to change this setting. However, setting S15 to
1 enables a special mode of operation in which data is forwarded as fast as possible for the data rate
for which the port is configured (at 115000 bps, this will typically be 2-3 ms).
Note that the default value of 0 is equivalent to setting the register to 2 to maintain compatibility
with older systems.
