Umm, why not?  What's wrong with saying I have a system with only a
few modems, maybe even only one like most users...and I want to allow 
dial in login but still be able to dial out.  The assumption is that simply 
you're willing to trade dialout for temporarily disabling dial in.

My alternative is to edit /etc/tty, HUP init, do my dialing, 
finish, edit /etc/tty, HUP init again, okay.  Now I maybe try to make
this automatic.  Hmm, a script wrapper around tip, cu, or kermit.
Hmm, sed? awk? perl?  Oh, yeah, hope things run to completion and clean up
properly.  This is less ugly than cua ??

With cua, I open() it, it works.  Something goes wrong and my program is
terminated (accidently or on purpose), the file is closed and things return
to normal.
