1. A computer switch comprising:
- a set of peripheral device ports for connecting to a set of peripheral devices;
a first port;
a second port;
a control device coupled to the first port and the second port, the control device repeatedly detecting whether the first port is occupied to repeatedly determine a master or slave status of the computer switch, whereinif the first port is occupied, the control device determines the computer switch to be a slave and provides data to a first external computer switch connected to the first port, andif the first port is unoccupied, the control device determines the computer switch to be a master and controls a second external computer switch connected to the second port and obtains data from the second external computer switch; and
a plurality of computer connection ports coupled to the control device for connecting to and controlling a plurality of computers, wherein the plurality of computers are controlled by the set of peripheral devices if the computer switch is determined to be a master, and are controlled by the first external computer switch connected to the first port if the computer switch is determined to be a slave.

Abstract
An intelligent computer switch is described. The intelligent computer switch has an automatic detection capacity to control a plurality of computers with at least one keyboard, at least one mouse and at least one monitor. The intelligent computer switch comprises an input port, a control device, an output port, and a plurality of computer connection ports. The input port receives input commands and data, and the output port sends output commands and data. While a series connection cable connected to the input port, the intelligent computer switch is determined to be a slave. While the series connection cable is not connected to the series connection cable, the intelligent computer switch is determined to be a master. The intelligent computer switch further comprises an on-screen display function and an authority-setting function with at least 4 sets of passwords for different users. Each slave generates a series number according to the sequence thereof and the master controls each slave according to the series number.
