We have tried all kinds of things to prevent and rid ourselves of zombied
ports. Patrick Latimer's program works well for cleaning them up after the
fact. Luke Bucklin suggested we try disabling xon/xoff for the telnet ports.
About 2 weeks ago we added the following to our port initialization program
(the dcd stuff was already there):

IF TELNET THEN
EXECUTE "DCD-ON"
EXECUTE "XONOFF (F"
END ELSE
EXECUTE "DCD-OFF"
END

The problem seems to be gone. Thanks Luke.
