AT-Q MNP10 Fallback to V.22bis
The -Q command permits the modem to fallback from a V.34, V.32bis or V.32 connection with
MNP10, to a V.22bis or V.22 MNP10 connection. MNP10 has the ability to make decisions
regarding line quality and will request a change in speeds if it decides the phone line is not
sufficient quality to maintain the current connection speed.
