Operating Mode
\N0 Sets normal mode.
\N1 Sets direct mode.
\N2 Sets reliable mode.
\N3 Sets auto-reliable mode.
\N4 Sets LAPM reliable mode.
\N5 Sets LAPM reliable mode with fallback to normal mode.
\N6 Sets LAPM reliable mode with fallback to MNP reliable mode.
Normal mode (\N0) can communicate with nearly any modem.
Error correction does not take place in normal mode.
Direct mode (\N1) does not buffer data and ignores flow control.
Also, in connect state, the serial port always adjusts to the speed
of the connection, regardless of the setting of \Jn. Error
correction does not occur.
Reliable mode (\N2) uses the MNP reliable link to provide error
detection and automatic retransmission of data if an error occurs.
This provides for error-free communications between your
system and another that supports the MNP reliable link. When
\N2 is in effect, the modem disconnects if it fails to establish an
MNP reliable link immediately after making a connection.
During an MNP reliable link, both modems should use flow
control on the serial port. When one detects a transmission error,
it holds data in a buffer while they retransmit.
NOTE You can use dial modiļ¬ers to set the operating mode for a
single call. See the D command description for details.
NOTE \J0 disables the escape code sequence in direct mode.
