NOTES:
• MNP 5 requires the modem to be configured for %C1.
• V.42 bis requires the modem to be configured for “H3.
• Refer to \Cn and %An commands for more information about auto-reliable mode.

The list of commands needed to enter a specific error correction or data compression mode are as follows:

V.42	bis with fallback to MNP5,	&F +ES=3,0,2	or	+ES=3,0,2 “H3 %C1
MNP2–4 or V.42:
V.42	bis with fallback to V.42/MNP2–4:	&F +ES=3,2,4 %C0	or	+ES=3,2,4 %C0 “H3
				-J1
V.42	bis only:	&F +ES=3,2,4 -J0	or	+ES=3,2,4 -J0	“H3
V.42	only:	&F +ES=3,2,4	or	+ES=3,2,4 -J0	“H0
		-J0 “H0
MNP5 with fallback to MNP2–4:		&F +ES=4,4,6	or	+ES=4,4,6 %C1
MNP2–4 only:		&F +ES=4,4,6 %C0	or	+ES=4,4,6 %C0

		Set Auto-Reliable Fallback Character: In auto-reliable mode (+ES=3,0,2) with auto-reliable fallback
		character enabled (\C2), receipt of the fallback character from the line during the V.42 detection phase
%An	13	causes the modem to switch to buffer (normal) mode. This allows a remote user with a non-V.42 modem
%An	13	to connect immediately with a V.42 modem. A space or carriage return is usually chosen for the fallback

		n = 0–127 (ASCII character)

		MNP 5 Data Compression Control: This command controls whether the data sent during the MNP
		frames is compressed using MNP Class 5 compression standard. MNP 5 data compression can improve
%Cn	1	throughput by as much as 150%.
%Cn	1	Range: 0, 1
		Range: 0, 1
		n = 0	No compression
		n = 1*	MNP Class 5 compression
