It's unlikely that under DOS or Windows that the two IP stacks would
know anything about each other. Even on OS/2; I've seen an OS/2 box
used as an applications gateway between two networks runing IBM's
TCP/IP on one interface and FTP, Inc.'s on the other, and there's
absolutely no (direct) interconnection possible between the networks
(as I'm told by those involved in the work.) The only way to get from
one network to the other would be to telnet into the OS/2 system and
then run the OS/2 telnet, e.g., that came with the TCP/IP stack that's
running on the remote interface.
