Ok, that took longer than expected because I was getting some strange statuses back. It turns out I had the B-Em tube speed set to 400% so, when the parasite requested that the host fetch the R1 status it wasn't waiting long enough for that to actually happen.

I am going to say B-Em now passes. There are some differences and these are cases where the defined behaviour is to return the last value and, as far as I can see, the test case doesn't set up what that should be. Here they are:

Code:

************************************************************    ************************************************************Testing HP1                                                     Testing HP1************************************************************    ************************************************************status                  hdav=0 hsav=1 pdav=0 psav=1             status                  hdav=0 hsav=1 pdav=0 psav=1parasite read   data=22 hdav=0 hsav=1 pdav=0 psav=1           | parasite read   data=00 hdav=0 hsav=1 pdav=0 psav=1parasite read   data=22 hdav=0 hsav=1 pdav=0 psav=1           | parasite read   data=00 hdav=0 hsav=1 pdav=0 psav=1
and

Code:

************************************************************    ************************************************************Testing PH4                                                     Testing PH4************************************************************    ************************************************************status                  hdav=0 hsav=1 pdav=0 psav=1             status                  hdav=0 hsav=1 pdav=0 psav=1host read       data=82 hdav=0 hsav=1 pdav=0 psav=1           | host read       data=00 hdav=0 hsav=1 pdav=0 psav=1host read       data=82 hdav=0 hsav=1 pdav=0 psav=1           | host read       data=00 hdav=0 hsav=1 pdav=0 psav=1
Everything else is now identical.
