When the modem establishes a reliable connection at speeds
between 4,800 and 16,800 bps with bps rate adjust enabled, the
serial-port speed adjusts to 9,600 bps. If the connection speed is
above 16,800 bps, the serial port adjusts to 19,200 bps. If you set
the serial port to the modem's highest rate of 115,200 bps, turn off
bps rate adjust to make sure that the serial port stays at 115,200
bps.

MNP Extended Services
-K0 Disables MNP Extended Services.
-K1 Enables MNP Extended Services.
-K2 Enables MNP Extended Services without MNP indication during
the answer detect phase.
MNP Extended Services allow two modems that support them to
use MNP data services that are not available with LAPM. For
example, negotiating MNP Class 10 with V.42bis compression in
preference to LAPM.
\K
n
Break Control
Where n is a number between 0 and 5 indicating the type of Break
the modem transmits (Default is 5).
Determines the type of Break the modem transmits when a Break
enters the modem. The following tables list the different effects of
the n value when the modem receives or transmits the Break. The
modem can buffer up to four Breaks on both the modem port and
the serial port.
NOTES Refer to the %F command description for information about
using the \J command during V.23 connections.
See the %Un command for information about resetting the
serial-port bps rate. When \J1\C0\N3 are set, the modem uses
direct mode instead of normal mode if a reliable connection is
not established.
We recommend turning off bps rate adjust (\J0) when using
data compression to retain the highest throughput.
