The mouse I have simply sends characters at 1200 baud; there's a "packet"-
like structure with a specific indicator for the "first" byte.  One byte
contains a bit to indicate the status of each of the mouse buttons. Other
bytes indicate the number of "ticks" the mouse has moved (x & y) since the
last packet.  If you'd like more info, or even a bit of Turbo-C code,
send me email.  I'll fetch stuff from home.
