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)

	Return (RETURN) or “Enter”. S3 may be set for
	any ASCII character.

	Feed. S4 may be set for any ASCII character.
