I'm trying to check out the Network Management Card in an Eaton 5P 850R. I'm running IPP 1.67 on Ubuntu 18.04 (all updates applied), this functions as expected proving comms from the 18.04 to the 850R is ok. In trying to connect to the NMcard via UPS Date/RS232 port I get:
[01:27:37:908] Connection established with 192.168.1.53
[01:27:48:900] NSM Connection closed with 192.168.1.53 after receive error
which cycles continuously.
Since Hyperterminal is not available on Ubuntu I've tried several alternatives, eg PuTTy, CuteCom etc, Hyperterminal is also not now available for Windows 10 where I've tried PuTTY which gives similar results.
The best I can get is by disconnecting and reconnecting the LAN cable:
