Odd Telnet Behavior

Testing VTX client only connecting to my BBS. Almost everything works great, except a few places where I see the client sending the text '@"' without the single quotes, the double quote included.

So: (AT)(Double Quote)

If I turn off telnet mode, and use raw it does not happen but I get some other characters appearing before screen clears and such which I am leaning to being the telnet codes.

I also have to use hixie mode, not sure exactly what it does but because I use WSS for my sockets, without hixie it does not connect. I have to use WSS as my pages are served over HTTPS.

Any suggestions for the @" issue? I can reproduce them anytime and I can get you into my system to test if you need.
