You should see a difference between no activity (timeout) and bad
information (unrecognized string returned). I suspect it will work
since the STB probably doesn't care which connection is being used
and will treat commands from either of them the same. Your mythtv box
will have no idea (or care) what kind of connector is on the other
end as long as the expected response comes back.
