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