\N V.42/MNP Data Connection
The \N command specifies what type of data connection your modem can establish
(MNP or LAPM (V.42bis)).
\T Set Switch Off Timer
The \T command instructs your modem to disconnect if no data activities take place
within a specified time (n), where n is between 0 and 90 minutes.
The default setting 0 disables the timer.
\N0 Establish a standard data connection (i.e., a connection that does not use
MNP or V.42).
\N1 Establish a direct data connection (i.e., a connection that bypasses error
correction).
\N2 Establish only V.42 or MNP data connections. If the partner modem does
not use V.42 or MNP, your modem aborts the connection and returns to
command mode.
\N3 Establish standard, V.42 or MNP data connections depending on whether
the calling modem uses MNP or V.42. If the partner modem does not use
MNP or V.42, a standard data connection is established. If the partner
modem uses MNP or V.42, one of these connections is established.
\N4 Establish only V.42 data connections. If the partner modem does not use
V.42, your modem aborts the connection and returns to command mode.
\N5 Establish only MNP data connections. If the partner modem does not use
MNP, your modem aborts the connection and returns to command mode.
\N6 Establish standard or MNP data connections depending on whether the
calling modem uses MNP. If the partner modem does not use MNP, a
standard data connection is established. If the partner modem uses MNP,
this connection is established.
Data flow control (&K) should be enabled during \N0, \N2 ,\N3, \N4, \N5, and \N6
operations.
