I think I've solved the problem a few users (including myself!) have experienced with Terminus 2.0a. I downloaded the complete Terminus 2.0a archive from Jack's support BBS and installed it from scratch. To my surprise, when I called a board that I'd been having trouble downloading files from, it worked perfectly – just like the original 2.0 version. I compared the phonebook of my original 2.0 Terminus to the 2.0a phonebook I created. The only difference was the 2.0 phonebook had this entry for nearly every board I call – "WINDOWSIZE = 64". When I removed the "WINDOWSIZE = 64" entries from my phonebook file, downloads (Zmodem and CIS B+) started working again! The "WINDOWSIZE = 64" entry didn't seem to effect the original 2.0 Terminus. Jack, what changed in 2.0a to cause this problem?
