我尝试使用串行端口api从串行端口读取数据:

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

但是，我在从android应用程序访问设备时遇到了问题。当我使用SerialPortFinder时，这是我找到的设备的日志。

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 08:56:52.394: D/SerialPort(2237): Found new driver rfcomm on /dev/rfcomm

02-28 08:56:53.074: D/SerialPort(2237): Found new device: /dev/s3c2410_serial1
02-28 08:56:53.074: D/SerialPort(2237): Found new device: /dev/s3c2410_serial0
02-28 08:56:53.204: D/SerialPort(2237): Found new device: /dev/ttyS3
02-28 08:56:53.204: D/SerialPort(2237): Found new device: /dev/ttyS2
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

我的Android（2.1）设备有一个rs232端口，波特率为2400;。

当我使用“new SerialPort（new File（deviceName），baudrate，0）；”

我唯一可以访问的门是“/dev/s3c2410_serial0”。

但是，这扇门与我的设备无关。

有人知道我怎样才能找到正确的端口，或者我是否做错了什么？
