C++ How to send extended opcodes from c++?

[lexus21]

I have code in OTClientV8 that reads a value from a COM device.
I want to send this value to the server (tfs 1.4.2)
How to send extended opcodes from c++(OTCv8)? or
Maybe I should switch the value to lua and send extended opcodes from lua?

I'm not sure if this committee serves you or not... This is detecting the V8 with OCPode and other types

I use tfs 1.4.2 without modifications and it has built-in opcodes. What you mentioned is tfs v8. This means that I have to implement the code from TFS_v8 to my tfs 1.4.2?

i use this code in otc_v8


CLIENT SIDE (OTC_v8 by otacademy)

/.../
g_logger.info(stdext::format("This is my output: %s", line));
ProtocolGame protocolGame;
protocolGame.sendExtendedOpcode(14, line);
/.../

SERVER SIDE (TFS 1.4.2)

in In data/creaturescript/creaturescript.xml

i have

<event type="extendedopcode" name="ExtendedOpcode" script="extendedopcode.lua" />

inside extendedopcode i have :

print("OPCODES WORK")

function onExtendedOpcode(player, opcode, buffer)
    if opcode == 14 then
        -- otclient language
        print("hey")
    else
        -- other opcodes can be ignored, and the server will just work fine...
    end
end

and login.lua

player:registerEvent("ExtendedOpcode")

and in OTC - terminal -

ERROR: Unable to send extended opcode 14, extended opcodes are not enabled on this server.
This is my output: 596

in TFS after launch:

/.../

Using LuaJIT 2.0.5

Loading lua libs

OPCODES WORK

extended opcodes don't work - what is wrong?

@Mateus Robeerto
I added these modifications to my tfs 1.4.2, still getting the error. Any advice

Little update.
I managed to send opcodes from OTCv8 using a module in lua to tfsv8.
So this code for sending opcodes dosen't
work

/.../
g_logger.info(stdext::format("This is my output: %s", line));
ProtocolGame protocolGame;
protocolGame.sendExtendedOpcode(14, line);
/.../

update.
this code

ProtocolGame protocolGame;
protocolGame.sendExtendedOpcode(51, line);

throw error : ERROR: Unable to send extended opcode 51, extended opcodes are not enabled on this server.

this code crashing client:

g_game.getProtocolGame()->sendExtendedOpcode(51, line);
