Need Wait or Pause (command or function)

[albaloops]

Hello Friend
I need the command Wait or Pause
Action Application.Sleep(Ms); Cause the all program to crash
For example :

SerialPort.Output(":7F10011200020400C8000090", "true");
Wait (1000) ;
   if (SerialPort.BufferCount()==0) then
    --do nothing
   else
    serialget=SerialPort.Input();
   end

I should be no interruption in the software. Why can not command Application.Sleep I use
In all programming language, there is a wait command
I'm surprised, because it without such the ability to

There is no sleep or pause in Lua because there is no sleep in ANSI C so you have to do something and that something on a single thread is going to make the app non responsive so the bundled Application.Sleep() function is about as good as it gets really but there is a few suggestions here along with here and also there is the WinApi Lua module that does have a sleep function but having tried that its only good for a second or two.

It seems the Application.Sleep() function although it says it does not respond to mouse clicks does not stop them being sent/recieved and its the clicking of the window that causes a crash when sleeping so try this before going to sleep.

This is probably better.
