FATAL ERROR: $SPOOL/etc/setup.cache is missing!

The file $SPOOL/etc/setup.cache is not present.  This
probably means the machine has not been setup using the faxsetup(8C)
command.  Read the documentation on setting up HylaFAX before you
startup a server system.

Subject: modem on $device appears wedged

The HylaFAX software thinks that there is a problem with the modem
on device $device that needs attention; repeated attempts to
initialize the modem have failed.
