NCSA Telnet with PC-NFS and Clarkson pktd.sys

[Karl Buck]

Greetings. I am trying desperately to get NCSA Telnet, PC-NFS to work
with the Clarkson packet drivers in our lab. Everything works great until:

	1. You exit Telnet
	2. You attempt to shell out (Alt-e)
	3. You exit FTP

In each instance the client machine locks up with the Network activity light
staying on constantly. 

After exiting telnet the following error comes up:
"run-time error R6001
 - null pointer assignment"

After some time dos comes back with:
"Not ready reading drive H" etc..

The client pc must then be rebooted.

The hardware/software is: 
	
	Server: Sun Sparc1 (SunOS 4.1)
	Clients: Fifteen 386 pc's with VGA running DOS3.3 and PC-NFS 3.0.1

Our configuration files follow (sorry for the length):

The config.tel file:
