Nut upsuser - Feb 2021 - SU5000RT3UPM support?

I have a Tripp-Lite SU5000RT3UPM that I?d like to get working with NUT. It?s
connected via serial to a RHEL 7.9 box.

Here?s what I get:

[root at micc nut]# /usr/local/ups/bin/tripplitesu -a tripplite -DD
Network UPS Tools - Tripp Lite SmartOnline driver 0.05 (2.7.4-2124-g9defa7a)
Warning: This is an experimental driver.
Some features may not function correctly.

addchar: discarding invalid character (0xe2)!
addchar: discarding invalid character (0x80)!

   6.508992 Unable to detect Tripp Lite SmartOnline UPS on port /dev/ttyS0

[root at micc nut]#


Any ideas? Has anyone gotten this working?

That's an older model and I don't know of any instances were we/someone
tested it with Network UPS Tools. You're using  the tripplitesu driver that
would have been my first guess.

If anyone has had success with the SU6000RT3UPM or the older
SU8000RT3UPM/SU10000RT3UPM that did NOT have USB ports, the communications are
effectively the same.

Is there a network card connected? I ask for 2 reasons:
1- Curious if you see any different results with the network card disconnected
2- It should support RFC 1628 (UPS MIB), which could allow for use of SNMP for
monitoring via NUT

Thank you,
