winpty/agent/Agent.h
Ryan Prichard 1fdda9e1d4 Work on console input handling.
* If bytes are still queued after processing as many keypresses as
   possible, send a DSR to the console.  The console should respond with
   a DSR reply, which will flush out the input buffer without having to
   wait for a timeout.

 * Add ah hoc code for ALT-<character> rather than listing every character
   in the table.

 * When keypresses have Alt/Ctrl/Shift modifiers, generate extra
   INPUT_RECORDS to press and release each modifier.  EDIT.COM seemed to
   require these for some Ctrl-<key> keypresses I tried.
