Re: [RTnet-developers] Ethernet IP

[Glen W. <gl...@je...>]

Hi All,


Well, I am now into my program.

I have rt_dev_select working and it detects an incoming TCP connection.

However, when I go to rt_dev_accept(), it returns function not implemented.
I can it find it use in any RTNET examples.

Any ideas?

Glen
