Re: [RTnet-developers] Ethernet IP

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

Well, I installed Xenomai and RTNET on a different distribution and
basically got the same issues as in the email below.

If I run accept() after select(), I get a -1 Invalid Argument error.

The rest is exactly alike.

I get these errors, even when I get the code as close as I can to the
RTTCP_SERVER example.

So there is either some problem with my insmods, some obscure program
setting or I have just found problems with TCP on RTNET.

At least the errors are in the same place both on RTAI and XENO_POSIX
