I'm sure it's been asked before, but I've not managed to find much. I have a 6 node qnx4 system, and wish to add some 
more hardware, which would ordinarily be another qnx4 node, running on a pc104 computer. I am considering running this "
node" under qnx6 to give myself the chance to learn this new fangled os. Are there any products/solutions that would 
allow my qnx4 system to message pass to the qnx6 machine via Ethernet? (other than resorting to tcpip sockets)

Thanks
