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:

\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:
