\J0:
Buffer mode. Error control selected (or not) by \Nn command (default).
\J1:
Force the max DCE rate to the DTE rate.
Result Codes:
OK
n = 0 or 1
ERROR

\Kn
Break Control
Controls the response of the modem to a break received from the DTE or the remote modem or the \B command.
The response is different in three separate cases.
The first case is where the modem receives a break from the DTE when the modem is operating in data transfer
mode:
\K0:
Enter on-line command mode, no break sent to the remote modem.
\K1:
Clear data buffers and send break to remote modem.
\K2:
Same as 0.
\K3:
Send break to remote modem immediately.
\K4:
Same as 0.
\K5:
Send break to remote modem in sequence with transmitted data. (Default.)
The second case is where the modem is in the on-line command state (waiting for AT commands) during a data
connection, and the \B is received in order to send a break to the remote modem:
\K0:
Clear data buffers and send break to remote modem.
\K1:
Clear data buffers and send break to remote modem. (Same as 0.)
\K2:
Send break to remote modem immediately.
\K3:
Send break to remote modem immediately. (Same as 2.)
\K4:
Send break to remote modem in sequence with data.
\K5:
Send break to remote modem in sequence with data. (Same as 4.) (Default.)
The third case is where there a break is received from a remote modem during a connection:
\K0:
Clear data buffers and send break to the DTE.
\K1:
Clear data buffers and send break to the DTE. (Same as 0.)
\K2:
Send a break immediately to DTE.
\K3:
Send a break immediately to DTE. (Same as 2.)
\K4:
Send a break in sequence with received data to DTE.
\K5:
Send a break in sequence with received data to DTE. (Same as 4.) (Default.)
Result Codes:
OK
n = 0,1, 2, 3, 4, 5
ERROR

\Nn
Error Control Mode Selection
This command determines the type of error control used by the modem when sending or receiving data.
\N0:
Buffer mode. No error control (same as &Q6).
\N1:
Direct mode.
\N2:
MNP* or disconnect mode. The modem attempts to connect using MNP 2
4 error control
procedures. If this fails, the modem disconnects. This is also known as MNP reliable
mode.
