Hi Somnath,

The SmbComOpenAndX code is based on analyzing communication of clients
that are so old I no longer have access to them (I think I would have
to resurrect Windows 98 somewhere). It is very possible that an
adjustment to the open flags is all that is necessary to get
SmbRandomAccessFile to work. But I would have to actually try it
myself. I cannot blindly apply a patch without high confidence that it
is correct. And an obscure router that doesn't implement commands that
have been standard for 20 years makes this a very low priority issue.
Never-the-less, I have added your diagnosis to the TODO list. It is at
least noteworthy that there is actually a device out there that does
not implement NT SMBs.

Mike
