We recently upgraded one of our production RTs (6150-135) to AIX
2.2.1.  After the upgrade we found that the system was not recognizing
a drop in carrier by our modems, and therefore not logging users out
if they accidently got disconnected.  No changes were made to the
modems during the upgrade.  I could not replicate this problem on our
production system.  In addition, some of the "modems" are actually T1
ADUs which also worked fine (thereby ruling out a
modem-incompatibility or setting problem).  Any ideas?  Please E-mail;
I don't get to read news that often.

Thanks in advance.
