Re: [hylafax-users] faxgetty+mgetty+login hangs.

[Stephen Kirkpatrick <stephenk@xxxxxxxxxx>]

What are the permissions and ownership on 'ttyS0' ?  When I've set up
dial-in services before, I have set the ownership of the tty device to
uucp and the group to a 'dialingroup' and the permissions 0660.  I also
added lines to mgetty.config for that port
   port-owner uucp
   port-group dialingroup
   port-mode 0660
