This is what's on Obsidian FServe script for xchat
Q: Hey the resume function is broken. Most files just won't resume.
A: I'm afraid it's neither my nor xchat's fault. The recent mirc releases have a broken implementation of the dcc resume protocol. While mirc understands it's own broken protokol most other irc clients will rightfully reject mirc's resume requests. Relax, it's not Your problem.
