Android access a device with serial port;

Question

I am trying to read data from a serial port using the serial port api:

http://code.google.com/p/android-serialport-api

But, i have a problem to access the device from my android application. When i use the SerialPortFinder that's the log with my found devices.

02-28 08:56:52.394: I/global(2237): Default buffer size used in BufferedReader constructor. It would be better to be explicit if an 8k-char buffer is required.

02-28 08:56:53.204: D/SerialPort(2237): Found new device: /dev/ttyS1
02-28 08:56:53.204: D/SerialPort(2237): Found new device: /dev/ttyS0

My android(2.1) device have a rs232 port, the baud rate is 2400;.

When i use the "new SerialPort(new File(deviceName), baudrate, 0);"

The only door that I can access is the "/dev/s3c2410_serial0".

But, this door is not related to my device.

Anyone know how I could find the correct port, or if I'm doing something wrong?

My problem was on the permissions, just unlock my root user on android, and it works!
