Digi W manual Registers Function Range Units Saved Default, Ascii

S-Registers

Register	Function	Range	Units	Saved	Default
	Rings to Auto-Answer
S0	Sets the number of rings required before the	0-255	Rings	*	0
	Digi Device Server automatically answers a
	call. Setting this register to Zero disables auto-
	answer mode.
	Ring Counter
S1	S1 is incremented each time the modem	0-255	Rings		0
	detects a ring signal on the telephone line. S1
	is cleared if no rings occur over an eight sec-
	ond interval.
	Escape Character
	S2 holds the decimal value of the ASCII char-
S2	acter used as the escape character. The	0-255	ASCII	*	43
	default value corresponds to an ASCII ’+’. A
	value over 127 disables the escape process,
	i.e., no escape character will be recognized.
	Carriage Return Character
S3	Sets the command line and result code termi-	0-127	ASCII		13
	nator character. Pertains to asynchronous
	operation only.
	Line Feed Character
	Sets the character recognized as a line feed.
S4	Pertains to asynchronous operation only. The	0-127	ASCII		10
	Line Feed control character is output after the
	Carriage Return control character if verbose
	result codes are used.
	Backspace Character
	Sets the character recognized as a backspace.
	Pertains to asynchronous operation only. The
	modem will not recognize the Backspace char-
	acter if it is set to a value that is greater than 32
S5	ASCII. This character can be used to edit a	0-32	ASCII		8
	command line. When the echo command is
	enabled, the modem echoes back to the local
	DTE the Backspace character, an ASCII space
	character and a second Backspace character;
	this means a total of three characters are trans-
	mitted each time the modem processes the
	Backspace character.
S6	Accepted but ignored.	2-255	s	*	2
S7	Accepted but ignored.	1-255	s	*	50
S8	Accepted but ignored.	0-255	s	*	2
S9	Accepted but ignored.	1-255	0.1 s	*	6
S10	Accepted but ignored.	1-255	0.1 s	*	14
S11	Accepted but ignored.	50-255	0.001 s	*	95
	Escape Prompt Delay
	Defines the maximum period, in fiftieths of a
	second, allowed between receipt of the last
S12	character of the three escape character	0-255	0.02 s	*	50
	sequence from the DTE and sending of the OK
	result code to the DTE. If any characters are
	detected during this time, the OK will not be
	sent. Note that sending of the OK result code
	does not affect entry into command mode.
