I have two customers that are utilizing the Digi Portserver TS-4 that are having the same problem. Multiple times a day the customer gets the message:
drp Sent Reset to node 0 - Improper Open Response
And the box stops responding. They have to unplug the power and plug it back in to get the box to respond again. We have reset the box at each location to factory default and we have removed and reloaded the software. Both sites are running SCO OpenServer 5.0.5. The devices are the only network-attached items having any problem, so I don’t believe its network related (we’ve changed the Cat-5 cable and port on the switch as well). Does anyone have suggestions as to the cause for this problem?
