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.
