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 unit 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 unit to switch from on-line mode to command mode.
S15 Data Forwarding Timer
Units: 10ms
Default: 0
Range: 0-255
S15 is used to set the data forwarding timer for the ASY port in multiples of 10ms. The
default data forwarding time is 20ms and in normal use this there should be no need to
change this. 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
115000bps this will typically be 2-3ms).
Note that the default value of 0 is equivalent to setting the register to 2 in order to maintain
compatibility with older systems.
S23 Parity
Units: N/A
Default: 0
Range: 0-2,5,6
The value stored in S23 determines whether the parity used for the ASY port is set to None
(0), Odd (1), Even (2), 8Data Odd (5) or 8Data Even (6).
S31 ASY Interface Speed
Units: N/A
Default: 0
Range: 0-11
