Hello Fabien,

yes I have all the options correct and I tried also with UTF8/Unicode but I think that the problem is that comfortclick doesn't establish a telnet session it just dumps/send the command to the specified address at the specified port.

Capturing ethernet data I see that the device receives the package containing the command as a text string inside the body of the ethernet packet.

If I connect through putty I see many more packets between my pc and the tesira that establish the connection and at the last packets I can locate the command that I send.

Reading this

it seems that tesira needs to establish a connection through session negotiation before accepting a command. From what I understand comfort click uses a "raw" connection as described in the Tesira documentation and for this type of connections it suggests the following

The control system needs to react to any incoming string that begins with 0xFF, and decide whether the option is desired or not. If the intent is to control Tesira using a ‘raw’ connection, all that’s required is to always reject the option negotiation. If Tesira sends a “WILL” Command, the control system shall respond with “DON’T”and if Tesira sends a “DO”, the response should be “WON’T”. The Option byte needs to be returned as received. In essence, the mechanism is as follows:

So is there a way to make comfort click to reject all session options and finally establish an actual tcp connection and send a command?

If not, does comfort click support the use of putty or any other program to establish a telnet session and send a command?

Ok tried again with a task but now three times and the monitor powered, thank you for your support.

Hello Fabien,

Thank you for your suggestion. I have tried the values that global cache has in their database and they don't work

For the time being I don't want any codes, if you know just tell me how I can send through comfort click one command two or more times.

I will figure out the rest.

It is a Sony monitor KDL-55W805C. From this post it says that the sony protocol needs to send the command three times.

I have success with two LG monitors that I use for testing and I can control them fine. The LG uses the nec protocol but Sony uses it's own.

Does anyone have tried to control a Sony TV or monitor?
