Oh! I understand now! You are going to take a joystick, disassemble it, and splice it together with your UPS so the buttons get pushed as you describe.
Pygame's joystick support is nice and simple and easy to use-- the only problem I could forsee is that AKAIK you have to initialize a pygame window before you can read joystick events. You said this was a server, so if it is not running a graphical environment, initializing that window could possibly be a problem. Otherwise, sounds like fun :) --- James Paige On Wed, Apr 13, 2011 at 04:55:53PM +0200, slawko.skrzy...@poczta.fm wrote: > 1) I am sure my UPS is neither being read as a Joystick nor any other device. > It is because it has only 2 connections: AC-input and AC-output. > 2) This UPS is made by "Ever" type "MP300". > 3) It is connected to the computer by AC-output socket on the UPS and > AC-input of the PSU in my PC.
