On most Unix systems, modems which auto answer should be setup in
the silent mode, that is no command echo and no result codes.
For a Telebit, this is controlled by the settings 'E0 Q1'.
However, if you are going to use the modem for bidirectional
calls, you must build a user specified A or B setting, which
contains the settings 'E0 Q1 S52=2' in addition to the other
values you want to set.  To save your A or B setting, use the &W0
command.  S52=2 forces the modem to reload your default A or B
settings every time the DTR line is dropped, which happens after
every call, both incomming and outgoing.  This enables you to
build dialing scripts which rely on 'E1 Q0', but have the modem
automatically reset itself after the outgoing call is finished.
