We’re trying to use QNX native networking over a serial line. We’ve set up
PPP on the serial line to the point where both machines are able to ping
each other, even by their local hostnames. When we use the mount command:
“mount -Tio-net npm-qnet.so” , the /net directory is created as expected,
but only with the local computer in it. When I try to do a “ls /net/mike”
(where mike is another computer), it says “no route to host”.
Here are the commands we’ve used:
both machines: io-net -ppppmgr -ptcpip
mike’s machine: pppd 115200 /dev/ser2 crtscts 10.0.0.2:10.0.0.1
mark’s machine: pppd 115200 /dev/ser2 crtscts
both machines: mount -Tio-net npm-qnet.so
We assume that qnet does not know how to use the PPP link to communicate.
The PPP link is up, but does it need some additional routing commands? Any
help would be appreciated.
Thanks in advance,
Mike and Mark

Maybe one of my reply lost 
What version of RTP have you installed? Get 6.1 
Any way, try this:
mount -Tio-net -obind=ip,resolve=dns /lib/dll/npm-qnet.so
Then, make sure “ping mike” works on “mark”, and
ls /net/mike (or ls /net/10.0.0.2)
