Preparing for upgrade to 4.0.3

[E Clinton Arbaugh]

The company I work for is preparing to upgrade to SunOS 4.0.3 from 3.5 Our
connection to the outside world is a slip line.  Before we do the upgrade,
I would like to know if anyone has had any problems/successes running slip
software with 4.0.3.  I can not see any reasons it wouldn't work, but then
again, I'd hate to not be able to read news. :-)

Thanks in advance.
