[Rxtx] Get RXTX working on MacOSX 10.6.7

[Chris Bartley]

Hi Dave,

Before proceeding with RxTx, have you verified that you can connect to your device from your Mac with a terminal program such as minicom?  I got minicom via MacPorts.  If that works, then RxTx should too.

This version of RxTx works for us with 10.6.x (and 10.5, as well as Windows 32/64 bit).  Binaries and source (both the unmodified and modified snapshots) are here:

	http://code.google.com/p/create-lab-commons/source/browse/#svn%2Ftrunk%2Fjava%2Flib%2Frxtx

Full details on how I built it (including changes I made to the RxTx source) are here:

You may also (instead?) want to check out the fork from Neuron Robotics:

I haven't had a chance to try it yet, but it sounds promising.

good luck,

Chris
