This is a bit weird also
PHP Code:
FakeClientCommandEx(param1, "say !datarate");
1st is the who making the client use the say command, instead of just issuing the sm_* command.
2nd why not just call the function instead where the command goes since it's within the same file:
PHP Code:
sm_datarate(client, 0);
sm_datarates(client, 0);
sm_serverdatarates(client, 0);
