</div>Interruptions do not cause failures on simplex. There is so much<br>
garbage that comes over the wire on the reflector that I imagine some of<br>
that has to do with it.<br>

</div>I don't doubt this a bit. Optimizing for the quiescent case seems to be<br>
the most effective thing to me. Even a small file will take ages to<br>
transfer if the protocol is patient enough to let people chatter while<br>
it's trying to do its work. I don't really think that trying to inject<br>
such extreme patience is particularly effective. What do others think?<br>

<br>
</div>These settings are effectively the same, so I'd attribute any<br>
variability to luck or Murphy.<br>

<br>
</div>100% voice traffic you mean? I can't see how trying to transfer data<br>
over an otherwise busy (with voice traffic) reflector is at all<br>
advantageous for either the voice or data users.<br>
<br>
For the quiescent case, the settings that you really want to try are the<br>
warm-up and forced delay. Setting forced delay to 6 (or more)<br>
seconds, with a warm-up delay of 0 and warm-up length of 64 might yield<br>
some interesting results.<br>
