. . but by no means all of it.

Now that I understand the routing problem I might be able to make it work with just the TCP/IP stack downloaded from IBM. Don't know if I'll get around to trying that though.

The way IBM set up routing on the 16-bit TCP/IP stack was a kludge to get around a problem. With the 32-bit stack apparently they fixed the real problem so the kludge became a problem.
