* Driver for the Logitech and ATI Inport Bus mice for use with 386bsd and
* the X386 port, courtesy of
* Rick Macklem, rick@snowhite.cis.uoguelph.ca
* Caveats: The driver currently uses spltty(), but doesn't use any
* generic tty code. It could use splmse() (that only masks off the
* bus mouse interrupt, but that would require hacking in i386/isa/icu.s.
* (This may be worth the effort, since the Logitech generates 30/60
* interrupts/sec continuously while it is open.)
* NB: The ATI has NOT been tested yet!
*/
/*
* Modification history:
* Sep 6, 1994 -- Lars Fredriksen(fredriks@mcs.com)
* improved probe based on input from Logitech.
*
* Oct 19, 1992 -- E. Stark (stark@cs.sunysb.edu)
* fixes to make it work with Microsoft InPort busmouse
*
* Jan, 1993 -- E. Stark (stark@cs.sunysb.edu)
* added patches for new "select" interface
*
* May 4, 1993 -- E. Stark (stark@cs.sunysb.edu)
* changed position of some spl()'s in mseread
*
* October 8, 1993 -- E. Stark (stark@cs.sunysb.edu)
* limit maximum negative x/y value to -127 to work around XFree problem
* that causes spurious button pushes.
