Hi Ali

I have seen some talk within the OpenRTE community about possibly porting
the system to VxWorks, but I don't really know where that currently stands.
I¹m not sure about the others. Part of the problem, frankly, is just having
access to systems for test purposes. Our community at present tends to
center around a few system platforms, so we are limited in our ability to
port/test.

Hopefully that will expand in the future.
Ralph
