A common ground between the computer and the connected serial device is mandatory. This is represented by voltage levels defined by the RS protocol. With RS, hot-plugging or hot-swapping is not supported, though it is sometimes possible to plug in a serial device and it will work while the computer is running.
With current technology, only a 9-pin connector is in use with most personal computers. A RS transmission begins with a start bit.
A start bit notifies the receiving computer of the incoming transmission. The data packets consist of 7 or 8 bit words. The data bits then follow the start bit on a LSB basis least significant bit - this is the bit with the lowest numerical value. A parity bit would generally follow the data, and then the transmission is ended with a stop bit.
A serial mouse comprises sensors, mouse controller, communication link, data interface, driver and software. Movement of the mouse as well as button clicks is detected by the sensors.

Notice: Try this at your own risk. I will not be responsible for any issues. If you are unsure, get a professional to help. There are 3 basic voltages for serial that are used. They are 12,5, and 3. You have to check the documentation of the devices you are using to be sure. Maxim and other companies make integrated chips to make the interfacing easier. You can also make you own circuits from discrete parts.
There are a ton of schematics on the internet to choose from. If you are unsure get a professional to help. Email Required, but never shown. The Overflow Blog. Podcast Making Agile work for data science. Stack Gives Back Featured on Meta.
