I have am relatively new to QNX, so this problem might be simple to solve for someone more experienced. I am trying to run an IP link over a serial port between a machine running Linux and one QNX Neutrino. (I am using the same options as I had successfully used between 2 Linux machines):
/usr/sbin/pppd /dev/ser2 nodetach debug
ppp0 : addr 192.168.0.1 netmask 255.255.255.0 up
Now the interesting bit, this is the debug message I get if I receive any datagram on the QNX side:
Protocol-Reject for unsupported protocol 0x3
rcvd [LCP ProtRej id=0x6 00 03 00 21 45 00 00 54 00 00 00 00 ff 01 3a 4d c0 a8 00 01 c0 a8 00 0a 08 00 fd ff 50 15 00 04 …]
So ping fails, nc only works with udp in one direction.
Thanks in advance,
