potential infinite loop on hangup (ring prompt)

Browse Source 
Core issue noticed while working on some Qt stuff.  If hangup
occurred while prompting for "right or left?" ring finger, the
hangup yn_function() would return ESC and the accessory-on routine
would not see '\0', 'r', or 'l' so reprompt.  Endlessly.
