(hmm a crosspost to -hackers and -questions, is that good?)

In article <015201bf7f4d$ac963e00$0301a8c0@Ptacek> you write:

Well the normal `unix' way to watch for CD is to turn off CLOCAL,
then you'll get a SIGHUP when the modem loses its connection.
(thats where that signal's name comes from, hangup.  people have
dialed into unix boxes over modems long before the internet got
popular...)  and to drop DTR you just do the equivalent of a `stty 0'.

 simple, eh? :)  (once you know it...)

 HTH,
