 Hi,
   I have just installed the NCSA_Telnet 2.2 on my IBM PS2/50 with 3Com
   3C523 MC card.  I have to said it is a wonderful software and I like
   it very much.  However, I have run into some problems when I set my
   PC as a workstation on the  Novell network.  I can start telnet and 
   login to other unix host on the campus network. When I try to 
   close the connection by using Alt-x key, NCSA_Telnet respone with a
   message:  Attempting to close . . .  and the PC will halt with the
   system message of     Internal stack overflow
                         System halt

   I have to power off the PC in order to rebot it.  The problem  will not
   occur if my pc is not boot up as a Novell workstation.  Is someone out
   there have experience with this kind of problem?

The NCSA code is trying to use the same network card as the Netware is.
They collide, and since Netware has its fingers very deep into DOS, it
crashes.  No cure, unless the Netware OEM does something which allows
interface sharing (e.g. implements our Packet Driver specification or
something like it), and you get a version of NCSA which uses that
software interface, rather than talking to the board directly.

A number of Netware OEMs have implemented interface-sharing (none use
3Com hardware, though), and TCP/IP which uses the Packet Driver spec
is available commercially from us, and in the CMU PC-IP and Phil Karn's
KA9Q freeware packages.  Some people at BYU posted a note about a generic
version of Netware they developed which calls the Packet Driver spec, too.
This would work on any hardware for which a packet driver is available,
but as of this moment, I don't know of a Packet Driver for the 3C523.

V1.05 of the Packet Driver spec is available for anonymous FTP from
vax.ftp.com, as pub/packet-d.ascii.  V1.08 will see the light of day
by 11/14.  Should I post it?
