Control Onkyo through tcp

[pouralise]

Hi, I want to control an Onkyo device through TCP using eISCP.  The protol information can be seen here at section 1.2
https://tascam.com/downloads/tascam/790/...otocol.pdf

I found out some other code to control it using php
https://www.domoticz.com/wiki/Onkyo 
or ruby

I use this python code and it work perfectly from my computer

I try to make some code like below to power on the Onkyo from LM but it didnt work

Code:

cmd = 'ISCP\x00\x00\x00\x10\x00\x00\x00\x08\x01\x00\x00\x00!1PWR01\x0D'
require('socket')
sock=socket.tcp()
sock:settimeout(2)
a=sock:connect('192.168.1.100',60128)
b=sock:send(cmd)

Can you help me to make this code work? Thank you very much

The command looks correct. What do you get as a result for connect/send?
