ARM - OE Linux, Java and SerialPort

ARM - OE Linux, Java and SerialPort

[Jan Pannecoeck]

Hello everyone,

I'm not sure if this is the right mailinglist, but I'll post my question 
here so maybe someone could help me. I'm currently using an OE linux 
distribution on my ARM board, this is all working fine and I'm using 
jamvm to run my java programs. Now I would like to communicate with a 
SerialPort. But the Java Communication API provided by Sun does not 
support an ARM based system. Only the Linux x86 system is supported. 
Since Linux is using the serial port as a "file", the reading and 
writing part could probably be done using a simple Reader and Writer in 
Java, but how can I change the baudrate and other configuration settings 
of the serial port?

Does anybody has any experience with this?

Kind regards, and a early happy christmas!

I had also contacted the distributor of my ARM-development kid (Taskit) 
they also gave me this advice, and I'm currently using the rxtx package!

Thanks!

You can read 《linux device drivers》and found out a "way" to control the 
SerialPort ,all operation is using a "file" interface. Good luck!
