And yes, there are two printers attached. The 820 is for sale.
And, sort of as an afterthought, lemme toss in that the Belkin Bulldog
UPS monitor soft, runs on a real serial port, /dev/ttyS1, hasn't
worked since about 2.4.18 or so. Somewhere about that time anyway.
I've yelled at Belkin since it was compiled on a RH5.2 system and
they've refused to update their proprietary drivers. Or to release
the API even if I'd have signed an NDA. NDI why.
