Table 21. V.44/V.42/V.42 bis and MNP Data Modem Command Descriptions (Continued)

Command	Default		Description

		V.44 Data Compression: This command controls the V.44 data compression function if provided in the
		DCE. It accepts the following sub parameters:
		m=[<direction>[,<compression_negotiation>[,<capability>[,<max_codewords_tx>[,<max_codewords_rx>
		[,<max_string_tx>[,<max_string_rx>[,<max_history_tx>[,<max_history_rx>]]]]]]]]]
		<direction> specifies the desired direction(s) of operation of the data compression function.
		0	Negotiated… no compression
		1	Transmit only
		2	Receive only
		3	Both directions, accept any direction
		<compression_negotiation> specifies whether or not the DCE should continue to operate if the desired
		result is not obtained.
		0	Do not disconnect if Rec. V.44 is not negotiated by the remote DCE as specified in
			<direction>. Always set to 0.
	3, 0, 0,	<capability> specifies the use of stream method, packet method, multi-packet method.
	3, 0, 0,	0	Stream method
	471,	0	Stream method
	471,	1	Packet method
	942,	1	Packet method
	942,
+DS44=m	140,	2	Multi-packet method
	140,	<max_codewords_tx> specifies the maximum number of codewords which should be negotiated in the
	1884,
	1884,	transmit direction.
	3768	transmit direction.
	3768	256 to 65536
		256 to 65536
		<max_codewords_rx> specifies the maximum number of codewords which should be negotiated in the
		receive direction.
		256 to 65536
		<max_string_tx> specifies the maximum string length to be negotiated in the transmit direction.
		32 to 255
		<max_string_rx> specifies the maximum string length to be negotiated in the receive direction.
		32 to 255
		<max_history_tx> specifies the maximum size of the history buffer to be negotiated in the transmit
		direction.
		≥ 512
		<max_history_rx> specifies the maximum size of the history buffer to be negotiated in the receive
		direction.
		≥ 512

		32-bit Frame Check Sequence: Controls the use of 32-bit frame check sequence option in V.42.
+EFCS=m	0	0	Use 16-bit FCS
+EFCS=m	0	1	Use 32-bit FCS if available in remote DCE; otherwise use 16-bit FCS
		1
		2	Use 32-bit FCS if available in remote DCE; otherwise disconnect
