  you can give my system a try... i do have IDS/IPS monitoring so you may be  
  blocked if your setup does initiate several connection attempts at once...  
  while we're talking about frontdoor and file transfers in the terminal, the  
  problam may very well be on the BBS side with whatever zmodem engine they  
  are  
  using... IIRC, my BBS offers more than one zmodem implementation... see how  
  one  
   works and change to another if needed...
