It would be nice if it were that easy to port PCIP to OS/2.  Regrettably, it
isn't.  Read the NDIS spec carefully, and find out all the details on dual-mode
pointers.  They make it very difficult to put C code in the OS/2 kernel, and
the NDIS spec only applies to Ring 0 code.  You could bring the NDIS spec out
to Ring 3 programs, but then you'd run into the problem of how to interface
to the LAN Manager (the redirector interface is secret, presumably to spite
Novell).

It could certainly be done (Microsoft is working on a port of Excelan's card-
resident assembly language TCP/IP to the OS/2 kernel, and HP/3Com are working
on something, and we're working on a port of PC/TCP), but it isn't a
lightweight job.
