   Log Message:   
   Fix telnet binary mode tracking.   
      
   When SyncTERM started by enabling binary mode in both directions,   
   the internal tracking of the binary status wasn't updated, so it   
   was incorrectly tracked as being in NVT mode.  After a file   
   transfer, it would then revert to the NVT mode it throught it was   
   in.   
      
   This change updates the binary mode value when sending as well as   
   receiving TELNET_BINARY_TX.   
      
   This is still technically broken though since binary mode is   
   negotiated separately in each direction, and the initial send of   
   WILL + DO is actually a pair of requests that need to be confirmed   
   by the remote.  Until they are confirmed, the connection is still   
   in NVT mode.   
      
   Hopefully though this isn't an issue since the remote should reply   
   to both, and if it denies there's no effective difference between   
   what we should do when already in binary mode and not because we   
   don't support any other modes (such as CHARSET option).  Fixing it   
   correctly would get very complex and involve blocking the connection   
   until we get a response.
