[Nut-upsdev] 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.

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.> > _______________________________________________ > Nut-upsuser mailing list > Nut-upsuser at alioth-lists.debian.net > https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuserCheers, Gene Heskett, CET. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
