Hmm. As it turns out, I can more or less reproduce this on the client-test mud I'm running. I can disable it fine, but sending IAC DO TTYPE results in not a single response from MUSHclient.

Removing the next step from my negotiation sequence did the same thing, which confuses me personally, but at least I'm not alone in my confusion. :)

I think I know where the don't was coming from: a reply to my request for TTYPE, the IS/SEND subnegotiations. Maybe...

The weird thing is, Mushclient still responds to TTYPE subnegotiations if TTYPE is off.

EDIT: Just tested by setting up a raw server connection in Ruby and sending IAC SB TTYPE SEND IAC SE, and MUSHclient does indeed reply. So that's a bug too, albeit not a particularly onerous one.

Twisol, I think that was for legacy MUD servers that asked for a termtype without negotiation for it properly beforehand.

After carefully looking at the code, I finally worked out. There was a bug in the WONT handling, where it did not properly reset the flags, which should have allowed it to send a WILL afterwards. Fixed in version 4.76.

Yeah, that's what I figured. Not completely correct by the spec, but there's no real harm to it. A strict client would simply ignore it, leaving the MUD no better off.

Thanks for this, I appreciate it.

While you have that area of code possibly still on your mind, could you look at MXP as well? It's doing the same thing to me, now that I'm testing it.

The fix will be a general one for when you send a DONT.

Thanks for all this, this is the first time I've reported something (not here) and had it worked on and fixed in such a quick manner. You guys rock.
