What happens if one tries to write to a protocol.transport that is not<br>
connected or in an error state? (I'm hoping that this case has defined<br>

Is there some way to query a protocol to see if it is in a good state<br>
(connected and no errors)? I realize with callbacks this is not usually<br>
necessary, but I have a case where it would be helpful (though I can<br>
probably manage without it).</blockquote><div><br></div><div>Can you elaborate on the case?</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

When reading raw bytes, is there any way to get the bytes from the<br>
protocol? I assume not: that if one wants to buffer the data one must do<br>
that in the callback. If so, does Twisted provide a suitable buffer<br>
class?</blockquote><div><br></div><div>The protocol gets dataReceivrd called. What kind of buffering do you want to do and why? Would a simple StringIO suffice?<span></span></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
