qnx over tcp/ip

I have a Qnx 4.22 (in a 486 IBM )whithout TCP/ip protocols, I need to connect this Pc into a little net. Anybody Know some place to download the protocol to put into a qnx?

I also reply to the newsgroup:

To my knowledge there is no free TCP/IP stack for QNX4. Unless you can find an open source one and port it yourself. Definitely NOT a trivial task, just interfacing with Net to get raw packet can be a challenge.

In fact I’m not sure there ever was a TCP/IP stack for QNX4.22 (were almost all processes are 16 bits)

For example sics.se/~adam/uip/

Even porting an open source tcp/ip stack should be really difficult ;)
