Okay, will read a bit. I contacted a friend of mine who has a logic
analyzer, so I can figure out if it's actually a standard serial
connection, and if so I'll try to find a Windows machine and sniff the
serial connection. :)
The custom cable with the optiups driver didn't work out by the way.
I probably should've checked the original cable first... if it's a
standard RS232 DB9 connection, I might have fried something now when
connecting UPS DSR (Input) to PC Tx and UPS DTR and RTS (Output) to PC
GND. (Okay, after researching the pins it sounds to me as like nothing
too serious _should_ have happened)
Well, you're always more clever after you fucked up. :D
