   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...

   Do you manage your own servers? If you are not running an IDS/IPS yer doin' it
