I have a copy of NCSA 2.2TN from Clarkeson that I'm going to try to install.  Unfortunately the documenation doesn't mention what NICs it supports.  I have a copy of Hank Nussbacher's PC/IP Scorecard and it says Telnet does not support the card I need, 3Com 3c503, except when you use 
the packet drivers package which is apparently different from the package I have.  My questions, in no particular order:

	1. Is there a driver for the 3C503 card available for the NCSA
	Telnet package from Clarkeson?

	2. If so, where can I get it (by e-mail, as I don't have FTP
	access anywhere but locally).

	3. Just what is a packet driver and how does it relate to other
	NIC drivers?

	4. Anyone have any suggestions for texts on how to write device
	drivers?  I've never written one and want to know how they work.
