Computer in the EX TMS was swapped out for one that can run MEDMs.  BOSEM signals were displayed on the screen, but did not change with BOSEM flag alignment.  We swapped cables at TMS to verify that that wasn't the problem.  Jeff spent a fair amount of time on the phone with Dave looking into the software situation.  The outcome of that was that it appears to be a hardware issue.  Dave did some further diagnostics, however it's late enough in the day that a fix will come tomorrow.
