AT Command Reference (continued)
\J	Bits/s Rate Adjusted

This command determines whether or not the negotiated connect speed of the modem forces the adjustment of the speed of the DTE to the modem’s speed.

\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		Otherwise
\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:

\K1:

\K2:

\K3:

\K4:

\K5:

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	Otherwise
\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 2¾4 error control
mode.	procedures. If this fails, the modem disconnects. This is also known as MNP reliable
mode.
