It is the default configuration. So you don't need to do anything.

You should differentiate between the case where the modem tells the
computer that it hung up the line (DCD drop), and the case where the
compter tells the modem that it should hang up (DTR drop). The first
is controlled by the CLOCAL flag, and works only for ports that have
modem control. The latter is controlled by the HUPCL flag.

>From your previous postings I had the impression that your problem
is that your computer doesn't tell the modem to hang up. This has
nothing to do with CLOCAL and modem control, but rather with HUPCL.
But I still have no idea what's going wrong on your system. On other
ESIX systems FAS 2.08 works as expected. There has to be some detail
that you didn't tell us yet. For instance, did you check the state
of the HUPCL flag just before the logout? Maybe one of your programs
clears this flag.
