AT Commands
*Q Recover Remote Access Configuration
Discards configuration changes you made during a Level 1 remote-access session but
did not save with an *U. The *Q or *U commands do not affect commands that
configure remote-access operation or telephone numbers that you added or changed.
NOTE
When you modify stored telephone numbers during a remote-access session, your
changes take effect immediately.
-Q
n Fallback Modulation Speeds
-Q0
Disables fallback from a V.32bis or V.32 MNP reliable connection to an MNP reliable
2400 or 1200 bps connection.
-Q1
Enables fallback from a V.32bis or V.32 MNP reliable connection to an MNP reliable
2400 bps connection.
-Q2
Enables fallback from a V.32bis or V.32 MNP reliable connection to an MNP reliable
2400 or 1200 bps connection.
Controls whether the modem can fall back from a V.32bis or V.32 MNP reliable
connection to a V.22bis MNP reliable connection at 2400 bps or a V.22 MNP reliable
connection at 1200 bps. Fallback may occur when poor telephone lines cause excessive
MNP retransmissions.
Fallback from a V.32bis or V.32 MNP reliable connection to a 4800 bps V.32bis or
V.32 MNP reliable connection is always enabled, regardless of the -Q setting. The
modem always uses the V.22 standard when it falls back from a V.32bis or V.32 MNP
reliable connection to a 1200 bps MNP reliable connection, regardless of the B setting.
:Q
n Kermit Mark Character
Where n is an integer from 0 to 31 indicating an ASCII character (Default is 1)
Defines the Kermit mark character the modem uses with the Kermit spoofing
asynchronous protocol enabled. This character must match the computer’s Kermit
mark character. Most computers use the default Kermit mark character (1). Both the
originating and answering modems must use the same Kermit mark character. See also
the :K command.
