6. From <vttoh@vttoth.com>. This is merely an observation. During testing,
   I sometimes initiated an ftp or telnet link and then Ctl/C-d out of it.
   Later, when the protocol went up, sometimes (not every time) the terminal
   (actually, telnet or xterm from another box) froze and needed to be shut
   down somewhat drastically.
   [still haven't tracked this down!]

10. There is most likely a problem in diald with disconnect that was
   inherited from pppd. We must be sure that the line discipline must
   be N_TTY on the modem before we run the disconnector.

12. The tcsetattr in close_modem always fails. Why?
