REDIRECT_STRING
This keyword is used to pass all strings from device 1 to device 2 and all
strings from device 2 to device 1. This is called a redirection and you can

The parameter Number identifies the particular redirection (1-8). To cancel a
redirection, pass zero for Device1 and Device2.
Note : Redirections are lost if system power is turned off.
