  I seem to be having a problem setting up dca0 on our 380. I can 'tip' to the
 modem and everything works fine. But when I disconnect, DTR on the modem stays
 on. So I cannot setup the modem to drop carrier at logoff. Is there a flag
 I need to set? The 9 pin to 25 pin cable works on pc's so I know the cable is
 ok and I tried setting up mdmbuf on ttys. Any help is appreciated.
 Here is the dmesg output. I The flags for dca0 was '1' but I switched it to
 0xe to see if that would help. No luck :-(.
