   Hi g00r00,   
      
   Thank you for taking the time to address each of the points raised; your   
   comprehensive response is very much appreciated.   
      
    g0> Blocking   
      
    g0> The only standard that I know of that ever attempted to define anything   
    g0> was Mystic's DOOR32 and that uses blocking sockets.  I assume you'd   
    g0> probably get blocking from most BBSes then by default, but I can't say   
    g0> for sure what other software does.   
      
    g0> I think it'd be a good practice to do this.   
      
    g0> The original intention was that the socket should be duplicated before   
    g0> being passed to the door, but I think in practice that didn't end up   
    g0> being guarenteed or even done at all because of variations in operating   
    g0> systems (and if I am not mistaken some OSes specifically said that   
    g0> sockets should not be duplicated).   
      
   I've decided to do the extra legwork and write comm routines which work   
   transparently for either blocking or non-blocking sockets - as winsock   
   doesn't detect socket mode reliably, this solution removes the headache of   
   socket mode altogether.   
      
    g0> It *might* be safe to call only when it drops but I can't say for sure   
    g0> without experimentation.   
        
    g0> If I remember correctly calling WSACleanup is a Windows specific thing   
    g0> and it invalidates any socket handles used by the process. For that   
    g0> reason I think it was not called in any case within D32 doors.  Instead   
    g0> it let the BBS detect the connection loss and do what it does.   
        
    g0> Things may behave differently depending of if/when the socket was   
    g0> duplicated by the BBS before being passed, but I would   
    g0> operate on the assumption that the socket is not duplicated.   
      
   Further testing appears to corroborate this: from what I can tell, WSACleanup   
   is best left to the BBS.   
      
   Again, thank you ever so much for taking the time to address these issues.   
      
   Best Regards
