In Java linux platform how can i connect to ttyS0 or ttyUSB0 for sending and receiving data?

I am trying to connect to a hardware, which works with my other operating system tools (such as minicom).

But now i am writing an application in Java to connect to that device using serial port RS232.

But which native way i should connect from Java? Should i use: http://204.93.165.39:8080/Giovynet/ ? Or is there FREE open so开发者_运维百科urce wrappers available for linux?

i used rxtx on windoze and it seemed to work ok. there is a linux version: http://www.agaveblue.org/howtos/Comm_How-To.shtml

i have some code that uses this that i can send to you.

I found this Wikibook on Serial Programming to be helpful.
