\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 states. The first state is where the modem receives a break from the DTE when the modem is operating in data transfer mode:

Command	Effect
\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:

Command	Effect
\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)
