Robbie, Let me make this observation. The DVDongle was originally written in Java to provide ease of programming and portability.
The overhead that it created was pretty high and is quite obvious when you compare the Java vs non-Java DVtool application. D-STAR requires a real-time operating environment. You've got to be processing on a very consistent basis at a relatively high pace. With a full stack, it is possible that you could have 400kbps worth of data to process. And these aren't big Ethernet packets, they are a whole lot of itsy bitsy UDP packets. In reality, a standard Linux kernel probably isn't the best solution, a RTOS or very small footprint Linux kernel is probably a much better choice. Something that runs in a classic router platform is a sooo much better design than a dedicated PC.

We had the following idea: Our preferred language would be Java. I see in your code snipped that you prefer this too. Let me (us) know what you think. 73s Robbie ON4SAX
