Multi-Tech Systems MT5600SMI-32 Command Operating Mode Error Correction, Command Identification

			Chapter 5 – AT Commands, S-Registers, and Result Codes
Command:	\N	Operating Mode - Error Correction
Description:		Controls the preferred error-correcting mode to be negotiated in a
		subsequent data connection. This command is affected by the OEM
		firmware configuration.
Default:		5
Defined Values:		\N0	Selects normal speed buffered mode (disables error-correction
			mode). (Forces &Q6.)
		\N1	Serial interface selected: Selects direct mode and is equivalent to
			&M0, Q0 mode of operation. (Forces &Q0.) Parallel interface
			selected: Same as \N0.
		\N2	Selects reliable (error-correction) mode. The modem will first attempt
			a LAPM connection and then an MNP connection. Failure to make a
			reliable connection results in the modem hanging up. (Forces &Q5,
			S36=4, and S48=7.)
		\N3	Selects auto-reliable mode. This operates the same as \N2 except
			failure to make a reliable connection results in the modem falling
			back to the speed buffered normal mode. (Forces &Q5, S36=7, and
			S48=7.)
		\N4	Selects LAPM error-correction mode. Failure to make an LAPM
			error-correction connection results in the modem hanging up.
			(Forces &Q5 and S48=0.) Note: The -K1 command can override the
			\N4 command.
		\N5	Selects MNP error-correction mode. Failure to make an MNP error-
			correction connection results in the modem hanging up. (Forces
			&Q5, S36=4, and S48=128.)
Result Codes:		OK
		Otherwise ERROR
Command	I	Identification
Description:		Causes the modem to reports the requested result according to the
		command parameter.
Default:		4
Defined Values:		I0	Reports product code (e.g., 56000).
		I1	Reports the least significant byte of the stored checksum (e.g.,
			12AB).
		I2	Checks ROM and verifies the checksum. Reports OK or ERROR.
		I3	Reports ROM Code Revision-Modulation (e.g., 2109-V90).
		I4	Reports OEM defined identifier string in binary format (default) or
			ASCII formats. (e.g.: a007040284C6002F bC60000000
			r1005111151012000 3000111170000000).
		I5	Reports Country Code parameter (see +GCI).
		I6	Reports modem data pump model and internal code revision.
Result Codes:		OK
		Otherwise ERROR
Command:	+GMI	Request Manufacturer Identification
Description:		Causes the modem to report the modem product manufacturer.
Typical Response:		+GMI: Multi-Tech
		OK
