This is a serial mouse driver, which is compliant with Plug and Play, supports dynamic detection (via serenum) and removal (either hotplug or via the device manager). The code serves as a sample for any serial-enumerable device. The behavior of the various routines is documented in the source code files.
These routines transmit and receive serial data using two general
* I/O pins, in 8 bit, No parity, 1 stop bit format. They are useful
* for performing serial I/O on 8051 derivatives not having an
* internal UART, or for implementing a second serial channel.
