Package: cupsys
Version: 1.1.23-10

When we upgraded from woody to sarge, we noticed that our serial printers (we
use a cyclades serial board) stopped working. Raising the debug level in
cupsd.conf from info to debug, we noticed in /var/log/cups/error_log that the
file /usr/lib/cups/backend/serial was missing. 

To solve this issue, we created a symbolic link using the following commands:
  cd /usr/lib/cups/backend
  ln -s ../backend-available/serial .

So after restarting cupsys everything started working normally.

Sorry for inconvenience, but this is specification since Sarge.
serial backend may cause serious problem such as hang up if user
connects modems, UPS, or other machines via serial port.

Please check "Backend Configuration" section in
/usr/share/doc/cupsys/README.Debian.gz.
You can enable serial backend by doing "dpkg-reconfigure cupsys".
