[ct-user] Strange thing happening on a hub

[Ted Bryant]

I'm assuming you are running DOS and you have the same DOS version on each computer.  Also, I am
assuming you are using the same version of CT on each machine.  Your hub, network cards and NETTSR
are apparently working OK, otherwise a computer with the non-working NETTSR wouldn't communicate
with anyone.  So look for something else.  It sounds like computers 2, 3 and 4 may all have the same
station number. Check to see if you have any duplicate station numbers.  Make sure each computer is
assigned a DIFFERENT station number in the CT setup.  This number is displayed top-left just above
the log, "Stn x".

This might be a hardware problem, but maybe someone here has seen it has a software problem.  I am
running (or trying to run) NETTSR on five TP 770s, with 3C589D PCMCIA cards.  I can get two
computers to talk to each other via a cross-over cable.  But, when I plug them into a hub with a
patch cable, I get results like this:

Computer one can broadcast and receive from all computers.
Computer two can only communicate with computer one.
Computer three can communicate with computer one
Computer four can communicate with computer one
etc.

All the computers have different "IP addresses."  I am using the EN106TP hub.  I have tried hooking
up one computer via a cross-over cable to the hub, and switching one port to uplink (same result.)

Any ideas (besides simply getting another hub)?

Thanks,
