OK, upon an incomming call . . . . the comport speed reverts to the speed
stored in NVRAM (which was set by the last AT&W or eqiv).

Auto baud rate detect is a phenomenom that is experienced on the PHONELINE
side of the modem.  When the "comport" speed is locked it DOES
NOT ALTER FROM THE STORED SPEED.

The locked speed stored is the speed of the _LAST_ AT&W command.  That
is how one sets the LOCKED speed.
