Sure, that's what happening now. But that pty handling is a bit messy, since 
gdb already knows what output comes from inferior, it could just prepend it 
with some character.

Ok, then it's not clear to me either. There's specific packet in remote 
protocol ("OXXXX") which allows to pass arbitrary text from remote side to 
gdb. Is this what's printed with "@". Or there some other messages from 
remote that are also printed with "@" prefix?
