Is there Java library or framework for accessing Serial ports? [closed]

Answer 1

As andri pointed out RXTX is pretty much your best choice. There is an article on getting started with RXTX on Windows here (relating to RXTX 2.1).

Answer 2

The most common framework used for this is rxtx.

Answer 3

If free isn't necessary -- remember, your time isn't free -- then Serial IO SerialPort might be useful. It's the only thing I found that works as-is on all of the following:

• 32/64-bit Windows
• 64-bit Solaris (didn't test 32-bit)
• 32 bit Linux (didn't test 64-bit)
• Mac OS X

You do get source with the product, albeit with some weird and annoying build practices.

FWIW, I'm just a contented user, not affiliated with the company.

Answer 4

rxtx as the other posters have said. I've been using it and it works nicely. There is a problem if using nonstandard highspeed baudrates (multiples of 115200 e.g. 230400, 921600 are OK, but 1MB is not even if the hardware & underlying OS supports it), I've been told this will be corrected in rxtx 2.2.
