How to Connect ttyS0?

[linwea]

Hi,
my android device has RS232 com port(not USB to RS232),and Android-serialport-api can work in my deivce,I compile the source success,but the GNUIOtest.apk Always display "Can't find USB Serial Port",
How do I Modify the source to Connect ttyS0?
and in the source "CommPortIdentifier.getPortIdentifiers();" is return new CommPortEnumerator() ,the result is portIdentifiers always have not any Elements;the app can not find any port?
thank you very much!

I compile this code success ,and my android device has an RS232 port, it works on my device.you can set the SerialPortId as "/dev/ttyS0" to connect ttyS0,As the result of "Can't find USB Serial Port" I Think you haven't create the properties file named gnu.io.rxtx.properties in /system/etc/ directory. The properties file has to contain the following text.

gnu.io.rxtx.SerialPorts=/dev/ttyS0:/dev/ttyUSB3:/dev/ttyUSB4

That is import to make sure your program has the permission to read and write the directory of "/data/local/".

大神您好，请问这个您有不带日志输出的so库吗？这个死循环打印日志太恐怖了，我尝试下载源代码但是编译失败了。
