AT\K Break Control
The \K command determines how the modem will react when a break sequence is sent from your
computer or received from the remote modem. During error corrected connections the modem
sending the break determines how the receiving modem will react. During non-error corrected
connections, the receiving modem determines how it will react. The default break control setting
is \K5.
The following tables show how the modem will react when it receives a break sequence from
either the remote modem or your computer.
