Problem with Port in ARDUINO/Processing
Jan 13th, 2010, 8:44am  
Hello,
I am sending some data over serial from Processing to ARDUINO.
When I try to open the serial Monitor of Arduino to read the data I get the message that my port is already being used...and this makes sense. I am using in both processing and ARDUINO COM4 when I have one platform on the other conflicts and does not work.It depends what I open first, then the other application does not work.
Any advice?
Thank you

Instead of opening it exclusively in Arduino monitor, try using a serial port "sniffer"

As an example, RealTerm has such a function.

@romank
But Realterm's "spy" (if that's what you meant by "sniffer") function is not included in the free version.

@CyberCulture
What is the purpose of the "other application" opening up the serial port again?

If you just want to see the data (and NOT send data) portmon by sysinternals might help. Realterm's "spy" function is similar.

If you want to send data, then you have a problem. You want two applications sharing the same serial port.

If you know how to create simple network programs (sockets, etc) funnel might be good for you.

(use google) funnel.cc/Software/Processing

funnel acts as a server and takes control of the serial port. All programs that want to use the serial port should communicate with funnel using sockets (locally, or via the network). Uses Firmata protocol to control the Arduino.
