   Or ClearToSend (CTS) if you do 7-wire serial.

   Yes, I think both 0 and 1 byte free at my end is a possible response to   
   incoming packets when you have a hard time handling the incoming data   
   stream.   
      
   Telling the remote end you have only 1 byte left in the buffer is used   
   for instance when tarpitting spam sending email servers, to force them   
   to waste a lot of resources for every sent byte so that they are busy   
   creating packets for an email your server wont accept instead of   
   spamming others at that instance.
