Password cell qualifier Determines which callback extensions, if any, can be used with the password stored
in a specified memory cell, where
n
represents the memory cell (0-9). This command
does not affect use of the fixed callback extension
,F
which is administered by an
MMS controller. This command is not affected by factory defaults.
%F n =0
Disables the callback extensions stored with the password in cell
n
. The modem will
terminate any call which sends that password with a callback extension attached.
%F
n
=1
Permits the roving callback extension
,R
to be used with the password stored in
cell
n
. The password can be used without an extension, but the use of any extension
other than
,R
will cause the modem to terminate the connection.
%F n =2
Permits the phone cell callback extension
,C
to be used with the password stored
in cell
n
. The password can be used without an extension, but the use of any
extension other than
,C
will cause the modem to terminate the connection.
%F n =3
Permits the use of either the roving
,R
or phone cell
,C
callback extension with
the password stored in cell
n
. The password can be used without an extension.
