Can't use Hylafax with xen.

[David C. Chipman]

	Hi Erik, 

		Do the permissions change on the modem device file when
using Xen? I don't know if that's an actual string that you might see
from perror(3). have you tried running hylfax through strace(1)? That
should tell you the actual system-level error that is causing things to
fail. I hope some of these suggestions help you narrow down the issue
you're having. Best of luck! Later,
