task initialization thorough serial com port

[lovedeep]

I want to initiate a task by passing a string suppose "y" (from serial port) and it should remains active until vi doesn't receive another string suppose "n". Please tell me how can I do it?

Provide some details please. I don't understand what you mean by ' remains active'. What are you connecting your serial port to?

What is the point of attaching an llb that comes with LabVIEW?
