We still have an old FreeBSD 4.11-RELEASE-p26 machine lying around
only because it's using those Stallion multiport serial cards. It's
working, but it's quite annoying to keep such an old FreeBSD version
online. We had to isolate this machine into it's own network DMZ since
version 4.11 isn't covered by the FreeBSD Security team.

To get around this problem, we recently built another console server
with a Digi Digiboard PCI PC/Xem card on FreeBSD 6.2-RELEASE-p12. It's
working great, so we're going to ditch the old Stallion cards. Unless
of course someone ports the stl(4) driver to FreeBSD 7.x

If you'd like to read the documentation on how I've setup the console
server with both the Digi board and the Stallion cards, check
