Nut upsuser - Jun 2024 - Any ideas what protocol GE VH3000 UPS might talk?

Got a community question at
https://github.com/networkupstools/nut/issues/2466 with at least two users
(and UPSes) in trouble.

Curiously, they identify as 067b:2303 Prolific Technology like a common
USB-Serial dongle brand. Experiments with blazer and nutdrv-qx got no
reasonable response from the devices.

The cure Jim, is eliminate the prolific by replacing it with a FTDI 
dongle.  Prolific has a bug in its wakeup, throwing away the first byte 
rx'd. I threw mine into the out bin 2 decades ago. Was trying to use it 
to talk to a cm11a for a heyu interface.  Failed miserably.  Encourage 
owners to toss it and get the FTDI-usb<->serial which Just
Works.
