It's a good idea: there may be intervening kermit, UUCP, or minicom
connections to the modem that can leave it in a really weird state.

Dimitriy was fairly convincing about using ATZ, but I still think we
should have an AT&F in there somewhere to actually set it to factory
defaults. The need to use AT&F rather than merely ATZ will be unusual,
but it will drive the poor fax user apeshit when it happens because
it'll be caused by things like poorly configured kermit sessions.
