QNX to QNX over TCP/IP

I have to set up a link between multiple QNX networks and a central QNX
system over TCP/IP through X.25 Routers.


Do I have to do all messaging & transfers in TCP/IP, or is there a way to
configure the system so that all the QNX Nodes can see each other as nodes,
such that “cp / /20/xxx / /30/xxx” would still work over the TCP/IP link,
and maybe even be able to use QNX send/receive between globally registered

All sugestions greatly appreciated.
