Thanks for your answer. I meanwhile tried TIOCMGET and I can
sense the state of dcd. Unfortunately I can't continously check
DCD because this takes ernormous cpu time. Is there a possibility
to get a signal,intr or whatever, whenever the state of DCD changes?
If not, what could you think of I have to do to implement such
a feature?
