   Using trace and dump (as well as a network analyzer), we found that
   the [packet] driver will send packets fine, but apparently is not
   receiving at all.

When a packet driver will send but not receive packets, it is almost
always interrupt-related.  Be sure of two things: 1) that you are
specifying the same interrupt that the hardware is using, and 2) that
there are no interrupt conflicts.  Many Ethernet cards default to
interrupt 3, which is used by the second serial port.

   	NCSA Telnet comes up with the error message: "Warning, packet
   driver vector incorrect, using default search" when run.  The
   config.tel entry we've been using is:

   		hardware=packet
   		interrupt=0x60      ; (set with wd8003e.com as <int_no.>)

   and we've tried other software interrupts, in case that was the
   problem.  We've also tried including various other items in the
   congif.tel (like the ioaddr and mem. address of the card) with no
   further success.

When you use hardware=packet, comment out all hardware-related parameters,
such as interrupt=, membase=, etc.  Telnet can determine them on its own.

   	One more thing: Has anyone heard about packet drivers which
   will respond to snmp queries from the net?  That is a large reason
   we are looking at using packet drivers rather than NCSA's built-in
   interface.

I know that Cabletron is doing something in that vein, but I know nothing
more than that.
