I have recently installed two EtherNic ethernet network cards (16bit, 10Mbit/s,
64k cache) into two machines: 386sx and 486.

The cards came with a packet driver called ENPD.EXE, ver 2.03.

The driver loaded as promised and I was able to get the machines to connect
to an IBM RISC/6000 with a bit of effort.  I am able to rlogin, telnet, FTP,
etc..  However, whenever I do something BIG, the system hangs.

By 'BIG' I mean: transfer a large (>30k) ascii file, transfer a binary file,
do 'too much' ls/cd/etc that causes printed characters to be transmitted.

The foolproof way to hang it is to FTP a binary file.  However, the system has
hung a couple of other times just at the DOS PROMPT.  This to me sounds like a
driver problem.

Any ideas?  Serial # of card/software: IMC002 and 10-11102, if needed.
Could I just use a different driver?  I tried the others available, but no
such luck.
 
Thanks in advance, and PLEASE e-mail responses to me.
