S-Register Definitions

Following is a description of the S-registers that can be set.

Register		Function	Range	Units	Default
S0	Rings to Auto-Answer. Sets the number of rings required		0-255	Rings	0
	before the Digi device automatically answers a call.
	Setting this register to Zero disables auto-answer mode.
	Ring Counter. Specifies the current number of rings. S1
S1	is incremented each time the modem detects a ring		0-255	Rings	0
	signal on the telephone line. S1 is cleared when the
	existing connection is established or dropped.
	Escape Character. S2 holds the value of the ASCII
S2	character used as the escape character. The default		0-255	ASCII	43
	value corresponds to an ASCII '+'. A value over 127
	disables the escape process. That is, no escape
	character will be recognized.
S3	Carriage Return Character. Sets the value of the		0-127	ASCII	13
	carriage return character used when displaying
	commands or results.
	Line Feed Character. Sets the character recognized as
S4	a line feed when displaying commands or results. If		0-127	ASCII	10
	verbose result codes are used, the Line Feed control
	character is output after the Carriage Return control
	character.
S5	Backspace Character. Sets the character recognized as		0-32	ASCII	8
	a backspace, used to erase the last character typed on
	the command line.
	Escape Prompt Delay. The amount of time required			0.02
	before and after an escape sequence (+++) is entered in				50
S12			0-255	second, 20
	order for the modem to transition from data mode to				1 second
				ms
	command mode.
	General Options Status. Indicates the status of
	command options.
	• Default: 138 (8Ah) (10001010b)
	•	Bit 0: Ignored.
	• Bit 1: Command echo (En):

		1 = Enabled (E1). (Default.)
	• Bits 2 and 4: Quiet mode (Qn):
S14		0 = Display result codes (Q0). (Default.)			138 (8Ah)
		1 = Do not display result codes (Q1).
		2 = Disables “CONNECT” result codes (Q2).
		3 = Disables “CONNECT” result codes on incoming
		connections (Q3).
	• Bit 3: Result codes (Vn):
