Multi-Tech Systems, Inc. AT Commands for the MultiModem & SocketModem MT9234 Series (S000434H)
Transmit Break
Use this command in non-error-controlled mode. The command causes the modem
to transmit a break signal to the remote modem. The minimum break length is 100
ms and the maximum break length is 900 ms. The <break_time> parameter has
values between one and nine with each increment representing 100 ms. The default
of <value> = 3 corresponds to a length of 300 ms.
The command works in conjunction with the \K command.
AT\B<value>
<break_time> = 0–9 in 100 ms units
3 (300 ms)
OK if <value> = 0, 1.
ERROR if <value> ≠ 0, 1.
Break Control
Use this command to control the response of the modem to a break received from
the DTE, remote modem, or the \B<value> command. The command values are
different in three situations:
AT\K<value>
\K<value> – Modem Is Operating in Data Transfer Mode
The modem receives a break from the DTE when it is operating in data transfer
mode.
\K<value> – Modem Is in Online Command Mode During Data Connection
The modem is in the online command state (waiting for AT commands) during a data
connection, and the \B<value> command is received in order to send a break to the
remote modem.
\K<value> – Break Is Received During Connection
The modem receives a break from the remote modem during a connection.
OK if <value> = 0 to 5.
ERROR if <value> ≠ 0 to 5.
