Very Important, Use following information on your own risk;-) Most mouses are either built only for PS2 or only for Serial ports.

But some of the new mouses are manufactured to work on both ports. These mouses are called Combo Mouse and the appropriate adapters are supplied with the mouse when you buy it or can be purchased as an option or you can build one on your own.

Because of the nature of the ports the two kinds of mouses are not directly compatible. They don't send out the information in the same matter (different protocols) and don't use the same signal levels, PS2 mouses uses TTL logic signals (0-5 volts) and serial mouses use RS232 signals (typically +10 volts - -10 volts). When a mouse is built for operration on both ports, are setup with a DB9 pin used in serial mouses, these connectors have 9 pins and the serial mouse only uses between 5 and 8 pins. This leaves us with at least 1 spare line, this is the line that the PS2 data portion of the mouse will use for sending it's information.

So now we can figure out that, the adapters are designed to work on a particular make and model and are not usually compatible with all other mouses. There are millions of Mouse Manufacturing companies is the world.

Please do not ask me which make and model are combo mouse. The standard PS2 mouse does not use Pin 2 and 6 but the internal electronics in Combo Mouse are designed specially to use them to work on Serial port. That's Combo Mouse. What about Logitech Mouse? Ans: Until now the very important observation by us is that Logitech Mouse are NOT combo mouse. Therefore the Logitech Mouse made for serial port will only work on Serial port and for PS/2 will work only on PS/2.

In some countries there could be some combo models available but 99% of them are not the combo. For following all connections we may use these chart for transmission of Data via Serial Port.

IMPORTANT NOTE: These motherboard manufacturers are really funny people in the world. Many a times Pin assignments given to a specific unit is changed. May be they have their own reasons. I myself found following two different PS2 Mouse pinout signals from Motherboards, which I tried to find for a very specific problem.
