SerialNotFoundException when changing baud rate to 14400

[baptistelabat]

Arduino 1.03 on linux ubuntu 13.04

Here are the steps to reproduce the problem
Load the standard firmata example
Open the Serial monitor.
Change the baud rate (try different ones)

At one point, you will get the following error:
processing.app.SerialException: Error opening serial port '/dev/ttyACM2'.
processing.app.SerialNotFoundException: Serial port '/dev/ttyACM2' not found. Did you select the right one from the Tools > Serial Port menu?

Sometimes, I was able to solve juste by restarting arduino.

I don't now if it's related but after having this error, even after unplugging the arduino and restarting my computer, i was getting errors, and I had to open ~/.arduino/preferences.txt to set back the serial.debug_rate to 9600 manually (was saved at 14400).

This problem is related to RXTX, the native serial library we use to connect to tty devices. It will be replaced by JSSC in release 1.5.6 (the next next one). In the meanwhile you can try using one of the nightly listed here #1633 (comment)

@baptistelabat
is the issue solved with 1.5.6?

Hi, I made some tests with 1.5.6-r2. I was not able to reproduce the error (as I can not choose anymore 14400 baud, the menu is proposing 9600 then 19200); I imagine that's the correction? I looped through the values I could select, and had no problem anymore.
