CRD 1500 Modem/Charging Cradle Programmer’s Guide
\Nn, Operating Mode
Description
Controls the preferred error correcting mode to be negotiated in a subsequent data
connection.
\N0 Selects normal speed buffered mode (disables error-correction mode).
(Forces &Q6.)
\N1 Selects direct mode and is equivalent to &M0, &Q0 mode of operation.
(Forces &Q0.)
\N2 Selects reliable (error-correction) mode. The modem first attempts a LAPM
connection, then an MNP connection. Failure to make a reliable connection
causes the modem to hang up. (Forces &Q5, S36=4, and S48=7.)
\N3 Selects auto reliable mode. This is similar to \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 causes the modem to hang 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 causes the modem to hang up. (Forces &Q5, S36=4, and
S48=128.)
