CHAPTER 6: S-Registers
time an incoming ring signal is detected, S1
increases its value by one, up to a maximum of
255. If you set S1 to a value other than its default
value of zero, or if the value is increasing with
rings, this new value remains stored in S1 for
eight seconds after the last ring is counted, after
which time the value reverts to zero.
S2
Escape Code Character
Unit: Decimal equivalents of ASCII characters
Range: 0-127
Default: 43 (+)
Description: S2 defines the escape code character. The
default character is the plus (+) sign
(43 decimal), but may be set for any ASCII
character. Setting an S2 value greater than 127
results in no escape character, and therefore no
means of entering Command mode from On-
line mode without breaking the on-line
connection.
S3
Return Character
Unit: Decimal equivalents of ASCII characters
Range: 0-127
Default: 13 (^M)
Description: S3 defines the character recognized as Carriage
Return (RETURN) or “Enter”. S3 may be set for
any ASCII character.
S4
Line Feed Character
Unit: Decimal equivalents of ASCII characters
Range: 0-127
Default: 10 (^J)
Description: S4 defines the character recognized as Line
Feed. S4 may be set for any ASCII character.
