Multi-Tech Systems, Inc. SocketModem MT5600SMI Developer’s Guide 31
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 O EM
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 equ ivalent 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 &Q 5,
S36=4, and S48=7.)
\N3 Selects auto-reliable mode. This operates the same as \N2 ex cept
failure to make a reliable connection results in the modem fall ing
back to the speed buffered normal mode. (Forces &Q5, S36=7, an d
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 er ror-
correction connection results in the modem hanging up. (Force s
&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 significan t byte of the stored checksum (e.g.,
12AB).
I2 Checks ROM and verifies the checksum. Reports OK or ERROR.
I3 Reports ROM Code Revision-Mod ulation (e.g., 2109-V90).
I4 Reports OEM defined ident ifier 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 mode l 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
