Trying to list files from a Win32 client on our 3K has the following
interesting effects. dir and ls simply fail as if something is wrong
with the command on the server. quote LIST only partially responds, and
then any subsequent command result, while working, gets me the response
from the command before it. We are on 55, patched up to but not
including Express 3. Does anyone else see this behavior? Does anyone
know why this is?
