A-10APPENDIX A: S-REGISTERS

Register	Default	Function
		4	16	Change MR to DSR
		6	64	Disable the remote-access busy
				message.
		7	128	Disable V.32terbo.
S38	0	Sets the duration, in seconds, before a forced hang-up and
		clearing of the Transmit buffer when DTR drops during an
		ARQ call.
		This is provided to allow time for a remote device to
		acknowledge receipt of all transmitted data. Default = 0:
		The Business Modem immediately hangs up when DTR
		drops. If the Business Modem receives the ATH command,
		it ignores S38 and immediately hangs up.
S41	0	Sets the number of allowable remote-access login attempts,
		thus enabling or disabling remote access.
		The default setting of zero allows no remote login
		attempts, disabling remote access. A value of 1 or greater
		enables remote access. If the number of unsuccessful login
		attempts exceeds the limit set by this register, the Business
		Modem returns online and any further login attempts
		during the remainder of that connection are refused.
S42	126	Stores the ASCII decimal code for the remote-access escape
		character. The default character is a tilde (~).
S43	200	Sets the duration, in fiftieths of a second, of the guard time
		for the remote-access (~~~~) sequence.
S44	15	Sets the duration, in seconds, of the interval between losing
		carrier and reestablishing a connection.
S51	0	Bit-mapped register. See the beginning of this appendix for
		information about setting bit-mapped registers.

		Bit	Value	Result
		0	1	Disable MNP/V.42 for V.22 (1200
				bps)
		1	2	Disable MNP/V.42 for V.22bis (2400
				bps)
		2	4	Disable MNP/V.42 for
				V.32/V.32bis/V.32terbo
				(9600/14400/19200/21600 bps).
		6	64	Disable Selective Reject
S53	126	Bit-mapped register. (See the beginning of this appendix for
		information about setting bit-mapped registers).
