   I've been having problems accessing a gateway I'm trying to set up.
Thanks to everyone who's given me help tracking down the problem. Since
I don't have hop check or traceroute capabilities from my companies net,
I had to bug aa4re and ke9yq to help a bit.
   Here's what I've found out so far.... The machine is reachable via
it's radio port. It's ethernet card goes deaf after about 90 minutes
of use. It can happen in the middle of a file transfer or telnet session.
One minute every things ok, the next minute, it looks like the machine
died. You can still access it via the radio port however. It's the
ethernet card that has stopped working. If I then start an IP session
from the radio side that uses the ethernet card, it wakes up again and
can be accessed from the Internet side. 90 minutes later, it goes to
sleep again and you have to initiate a ip connect from the radio port
again. ( When I say radio port, it would also probably work from a local
keyboard, if the machine had one. It's a remote gateway )
   Does this problem sound familiar to anyone?  I'm going to see about
swapping the ethernet card for another one and see if that helps.  The
current card is an Micro Comm 5210?  Something like that.  It's running
a ftp clarkson driver.
   Thanks.

Looks like I jumped the gun a bit in blaming NOS. I added a CD-ROM and
ethernet board over the weekend. One of them is giving my bus-mouse
fits. If I load the mouse driver and run ANY large program, my system
slows down. I removed the mouse driver and the problem went away. I
should have thought of that, but it was really late by the time I got
both the CD-ROM and ehternet boards working. I didn't realize my mouse
was dead. Thanks.

Hi Jack...

Ah-HA!  I would hazard a guess that you installed the CD-ROM or the ethernet 
card without selecting the DMA channel for one or t'other. At least on 16 bit 
ISA based machines this can kill you and the mouse problem is 
"pathonemonic".Check and see if you can do that switch.... otherwise you will 
be software polling every non-DMA device on your bus... Bet your CPU is
saturated with polling time (plus processor heavy NOS/TSR's/DesqView/Windoze!)
and being choked to death!
