Mouse is usually connected to one of serial ports known to BIOS (their
addresses are at 0x40:0,2,4,6; I don't know any mouse driver using
other port and even if there is any, it must get port address from
command line or config file...). And: I don't know if there is any
possibility to send command to mouse (if there is a possibility to
send command to mouse and get answer, it makes possibility to check
where is mouse), the only I tried was to receive what mouse sends
and interprete it. But it should be enough: ask user to move the
mouse and wait until data received can be detected on any serial
port, then assume mouse is there. I took decoding algorithm from
some BYTE or other magazine, don't remember but have a program -
would you like to look at it ? (it is about 15kB of .ASM source).
