flow of the program

[scristian]

Hi

I have a vi program that read data from a serial port. It's a extension of advanced serial example.

Now I want to add 4 buttons to control the serial connection. A connect button to connect to the serial port, a Start button that write to serial port a command to start transmit data and a Stop button that write to serial port a command to stop transmitting. 

Can someone guide me to a easy way to control the serial connection ?

Thank you

You can do this quite easily with a simple state machine.

It looks like your're already confident with serial IO, and you just need to implement a good front panel and a control structure.

You may design your front panel first, then manage controls by an event structure. If you don't know how to use it, you may start here:
