RS232 Command for LG TV Not Working


I have already read the but it doesnt work.

When i connect my LG TV to my Windows Client (Serial, COM1), which runs the XIBO Player i can control the TV via Putty without any Problems with this Commands:

I have a Problem when i put the command into a Shell Command - i put this command in the Field “Windows Command” - rs232|COM1,9600,8,None,One,None,1|6B 61 20 30 30 20 30 31 0D

Why doenst work this on my Windows 10 client?

Thank You,
