AT\ Commands

\Kn - Break Control Controls the response of the modem to a break received from the DTE or the remote

modem or the \B command according to the parameter supplied.

The response is different in three separate states.

The first state 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 a break is received from a remote modem during a non-error

corrected connection:

\K0 Clears data buffers and sends break to the DTE.

\K1 Clears data buffers and sends 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.
