But isnt in telnet binary mode, 0xFF needs to be received twice consectively before the other end should interpret what should follow?
I must admit I havent read the finer details of how things are parsed when in it goes in this mode - but I assumed this mode assisted binary file transfers that are likely to have those special control chars that would normally be intepreted as IAC commands.
