The modem is support to drop the DCD signal when the carrier vanishes, and this should in turn send a SIGHUP to the process. This will eventually terminate the process even though the PPP layers haven't been shut down correctly. (Apparently, your other client's PPP implementations do shut down the layers properly, so your PPP volunteerely drops the connection itself.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
