-
- You don't need a new getty, as NXFax acts as the getty for the modem.
- It checks to see if the incoming call is a FAX call or a data call.
- If its data, then it runs a program (by default, /bin/login, I
- believe). All automagic.

-
- You don't have to play these games. The NXFax software determines on
- a call-by-call basis if its a data or fax call.

-
- Again, this isn't a problem on the NeXT with NXFax.

-
- As far as I know, the NeXT NXFax software is one of the few that just
- identify the call and do the right thing. Of course, I've not had the
- occasion to investigate Sun or other platforms.
