PS/2 to Serial Port Mouse Adapter is a device designed to convert the traditional PS/2 (Personal System Product) interface used by computers for controlling mice into a serial connection. It bridges the gap between older hardware and modern systems with USB-only ports. Typically made of a USB-to-串行（RS-232）转接器，这个小巧的转换器允许鼠标通过串行线缆与电脑连接，解决了那些PS/2接口过时电脑与鼠标之间的兼容问题。使用时，只需将鼠标的PS/2端口插入adapter，再通过串口线连接至电脑的串行口或波特率合适的USB转接器，用户即可继续正常使用鼠标。这种转换器简化了老设备的升级步骤，提升了系统的扩展性。PS/2 to serial port mouse adapter
