In Android, how is it possible to make serial ports (ttyS0, ttyS1) r/w for everyone?
<p>I've developed an app that listens to the serial ports and I've been using "chmod 666 /dev/ttyS0" for read/write access to the serial port - however - this method relies on "su" and is only temporary.</p>

<p>What needs to be done to gain read/write access to the serial ports permanently ?</p>
