joydrv_6551m is for a microsoft serial mouse, but I believe it has been 
broken for years.  joydrv_6551L OTOH I wrote back in 2008 originally, and 
that supports either a cheap logitech 'DeXxa' serial mouse, or a microsoft 
mouse that is contemporary to the logitech.  It inits itself in the M$ 
mode, but on detecting a MMB event from a logitech mouse, it sets itself up 
to handle the logitech mode until the next reboot.  The MMB packet is the 
only diff between those mice families.

So basically we only need 2 of the many choices, joydrv_joy.sb for a coco 
joystick, and I have no clue if it actually works with any of the rs mice, 
or joydrv_6551L.sb, which works with a serial port such as the rs-232 pack, 
or in my case a piggy backed dual chipped rs-232 pack that can also be used 
for a 2nd hardware serial port.  I think you will have to locate the 
hardware address of the port, and use xmode to make the module match that 
and verify it since that descriptor in the repo is coded for my extra ports 
address, $FF6C iirc, but my hand isn't anywhere near the good book on that 
point.  IRQS says $FF6D, which would be the stats register, so $FF6C is 
correct, for MY hardware. YMMV as always.
