OK, this is a little weird, but I have to do it.
I need to have one pc (A) control the mouse of another pc (B). PC A will be accessed remotely. Once PC A is accessed, it would somehow be connected to the mouse port on PC B. Remotely moving something on the screen (mouse icon, arrows, widget, etc.) of PC A would then emulate moving the mouse on PC B. PC A can be remotely controlled, PC B cannot. But, PC B needs to be remotely controlled. Nothing can be installed on PC B. The only way to control PC B is via the PS2 mouse port.
2nd question: does PCAnywhere have a remote camera feature? This way PC A could have a camera installed so you could see what you were doing on PC B (IF, we solve the 1st problem of controlling PC B via PC A mouse port).
This is a toughie!!
