command with serial console
 

I want to developp a real time application and I want to command my system with serial console.
The problem for me is to find a function that is non bloking my system. That's to say if a call the function it is able to see if there is an input or nothing and to execute ans pass to the next actions to do.

I used fgets but it wait for \n character so it is bloking if nothing

thanks for help

That sounds like a programming forum question. Anyway... maybe you have to fork the execution.
