remrec4.bat cannot send to romete controller

[zhjygit]

"If the Widucky types 'remrec4.bat dir/w', the batch file executes the the 'dir/w' command
and sends the output of the command to the WiDucky serial port.
The output is then returned via wifi to the controller application and displayed remotely.
(*This requires the Arduino drivers to be loaded on the target machine.)"

What is the mean (*This requires the Arduino drivers to be loaded on the target machine.)"???

the output of "remrec4.bat dir/w" is a file named msg.txt, however, it cannot be returned to the controller.
