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...
