    I'm using netbeans to develop an application to send and receive data via RS 232 standard.
    I can send data but I can't read it.what can I do?
    I have this message in the console: Underlying input stream returned zero bytes
    (I must use also threads to have application in real time but I don't understand very well

    Welcome to the forum! Please read this topic to learn how to post code in code or highlight tags and other useful info for new members.

    I don't see how there's much we can do to help you without seeing some code. We won't be able to duplicate your error, but there may be some here with experience using the RS232 library you're using who can spot errors in the code or apply their own experiences to give you possible solutions to explore.

    Provide more relevant details about what you're doing and how you're doing it.
