screen: Zmodem

 
 20.24 Zmodem
 ============
 
  -- Command: zmodem [off|auto|catch|pass]
  -- Command: zmodem sendcmd [string]
  -- Command: zmodem recvcmd [string]
      (none)
      Define zmodem support for 'screen'.  'Screen' understands two
      different modes when it detects a zmodem request: 'pass' and
      'catch'.  If the mode is set to 'pass', screen will relay all data
      to the attacher until the end of the transmission is reached.  In
      'catch' mode screen acts as a zmodem endpoint and starts the
      corresponding rz/sz commands.  If the mode is set to 'auto', screen
      will use 'catch' if the window is a tty (e.g.  a serial line),
      otherwise it will use 'pass'.
 
      You can define the templates screen uses in 'catch' mode via the
      second and the third form.
 
      Note also that this is an experimental feature.
