17 * Driver for the Logitech and ATI Inport Bus mice for use with 386bsd and
18 * the X386 port, courtesy of
19 * Rick Macklem, rick@snowhite.cis.uoguelph.ca
20 * Caveats: The driver currently uses spltty(), but doesn't use any
21 * generic tty code. It could use splmse() (that only masks off the
22 * bus mouse interrupt, but that would require hacking in i386/isa/icu.s.
23 * (This may be worth the effort, since the Logitech generates 30/60
24 * interrupts/sec continuously while it is open.)
25 * NB: The ATI has NOT been tested yet!

29 * Modification history:
30 * Sep 6, 1994 -- Lars Fredriksen(fredriks@mcs.com)
31 * improved probe based on input from Logitech.
32 *
33 * Oct 19, 1992 -- E. Stark (stark@cs.sunysb.edu)
34 * fixes to make it work with Microsoft InPort busmouse
35 *
36 * Jan, 1993 -- E. Stark (stark@cs.sunysb.edu)
37 * added patches for new "select" interface
38 *
39 * May 4, 1993 -- E. Stark (stark@cs.sunysb.edu)
40 * changed position of some spl()'s in mseread
41 *
42 * October 8, 1993 -- E. Stark (stark@cs.sunysb.edu)
43 * limit maximum negative x/y value to -127 to work around XFree problem
44 * that causes spurious button pushes.
