Hi Guido,

I’m not sure we have another protocol which supports switching back to plain 
text after going TLS. Therefore I’m not sure if there is intrinsic support for 
it. 
My first instinct would be to setup a new conversation, starting the frame 
after ‘close notify’, with the HiSLIP dissector assigned to it. I’m not sure 
how that would interact with the existing HiSLIP over TLS conversation though, 
so YMMV.
Hopefully someone else has a better idea.

Thanks,
Jaap
