Hi,

I'm using NetBSD 2.0rc4, hylafax and a Elsa MicroLink USB Modem. After
the start of faxgetty or any other program using the modem my netbsd
kernel crashes with a null pointer exception.
If I run "cu -l /dev/ttyU0" I can talk to the modem an everything is
fine.
I use a Dell PowerEdge 4600 machine.

Has anyone an idea what happens?
