We are attempting to connect an RF hand held bar code scanner to the HP3000
(well, a vendor is trying to do this for us).  We can see the hand held
connect to the RF access point, but as soon as the hand held attempts to
connect to the HP, the hand held displays a message about the TCP connection
being reset (presumably by the host).  However, I can ping the hand held
from the host (HP3000) while it has this display on it.  There is no ping
available on the hand held.  The vendor has taken the hand held back for
more testing (it's hard to believe they did any testing), and believes that
the software on the hand held is incorrect (we had a proof-of-concept demo
using a different hand held that worked fine).

If the vendor comes back to me and says that everything on the hand held is
okay, and that it must be that the host (HP3000) is rejecting the
connection, what can I do to either prove or dis-prove this?  I was thinking
of a packet sniffer or something that could trace the packets from/to this
hand held.  Would that show us anything helpful?

Any ideas are welcome.
