Something doesn't compute here. I don't believe the discussion has anything to do with whether you support positive ACK or not. If you're doing error recovery level 1 or above, then you are required to support it, because the other end is allowed to say A=1 and you're required to answer that. If you don't want to support positive ACK, the solution is to support only error recovery level 0. The issue under discussion is whether the rule "you are allowed to set A=1 only once per MaxBurstSize" is correct. At this point it's clear to me that it is not, because you need to be able to set A=1 at the end of the transfer. The current rule forbids that unless the total transfer size is >= MaxBurstSize. Kevin's proposal is a simple fix to this problem. paul
