However if you interpret "functionality" to include "does it function",
then the other issues are very relevant. We have had the experience
where a IEEE 803.2 transceiver would work, but a Version 2 transceiver
would not work. The difference apparently was in the shielding and
extra pins used in the connectors for the shielding. From my description
you can tell that I do not understand the problem very well and would
appreciate a reference to the complete differences (if it exists).
