[Nut-upsdev] AEG - PROTECT HOME support using NUT with serial protocol

[Joachim Schiele]

hi,

i own a aeg protect home (think it is a 600 VA) which has a serial and 
an usb port.

using this hack in ups.conf:
  [bestupsname]
        driver = bestups
        port = /dev/ttyUSB0
        ID = FOR,750,230,230,11.0,13.5
        desc = "home-server"

i start the driver with:
   ./bestups -a bestupsname -D -q

and after adding some debugging it seems to work (not yet in 
production). i first started by looking at the protocol and it is very 
very similar to www.networkupstols.org/ups-protocols/megatec.html at 
least protocol wise.

but i have a few problems

==== problem 1 ====
using FOR is wrong as it then reports as a different device than it 
actually is. should i add a new device string, say APH?

==== problem 2 ====
i would like to use the usb protocol but i don't know where to start.

maybe there exists such an implementation for usb already. last time i 
implemented the protecthome driver i found bestups to be what i actually 
wanted but then i already invested a lot of time in writing protecthome.c;


=== summary ===
maybe someone can help me with this problems. i will post a spec of what 
i have found so far in my blog soon.

thanks in advance
