Command Description
\J n BPS Rate Adjustment
If enabled, the serial-port speed will automatically be changed
to the modem-connection speed, forcing the user to change
the bps rate of the DTE-to-modem, if needed. If disabled, the
serial-port speed is independent of the connection speed,
which allows much greater throughput when using error
correction and data compression.
For example, if the initial DTE rate is 38,400 bps and the
modem connects to the remote modem at 9600 bps, the
modem automatically lowers its DTE rate and expects to
receive characters from the DTE at 9600 bps. For data transfer
to occur, the DTE rate must then be lowered from 38,400 bps
to 9600 bps.

\K n Set Break Control
This command defines what action the modem takes when a
break (Attention signal) is sent or received, as described
below.
NOTE: Using this command is not recommended unless your
communications software supports the Break character and
your application requires you to send or receive break signals.
The break signal is a special character, much like any other
byte of data received by the modem. If expedited breaks are
enabled, the modem acts on the break as soon as it is
received. Non-expedited means that the modem acts on the
break only after clearing any buffered data.
If destructive breaks are enabled, the modem discards the
buffered data.
The serial port is the connection between the PC and its
attached modem. The modem port is the connection between
the modem and the telephone line.
