freebsd-dev/usr.sbin/moused/moused.c
Peter Wemm 13379e47c1 gut and overhaul moused, it was simply not working for me on any mouse 
I could find.  This change does the following:
  - s/usage()/break;/ in handling the -s switch.
  - use err/warn instead of fprintf(stderr, ... strerror()); exit(1);
  - implement Hitachi PUMA HitTablet support from the XFree86 code,
    whatever the hell that is. :-)
  - correctly implement baud rate setting, too much was cut from the
    XFree86 code, the critical parts were a sweep over all likely
    mouse powerup baud rates to switch it to the reqested rate.
  - logitech support was busted (at least on mine, which is autosensing
    and runs in either mmseries or logitech mode depending on the handshake
    code at startup.  Among other things, you talk to it at 1200, then
    switch to the target baud later.

Some remaining problems..  samplerate setting is missing, but I've not
found where this is meant to be set yet.  I presume this is resolution
setting of some kind.

** The following lines take care of the Logitech MouseMan protocols.
**
** NOTE: There are different versions of both MouseMan and TrackMan!
** Hence I add another protocol P_LOGIMAN, which the user can
** specify as MouseMan in his XF86Config file. This entry was
** formerly handled as a special case of P_MS. However, people
** who don't have the middle button problem, can still specify
** Microsoft and use P_MS.
**
** By default, these mice should use a 3 byte Microsoft protocol
** plus a 4th byte for the middle button. However, the mouse might
** have switched to a different protocol before we use it, so I send
** the proper sequence just in case.
**
** NOTE: - all commands to (at least the European) MouseMan have to
** be sent at 1200 Baud.
** - each command starts with a '*'.
** - whenever the MouseMan receives a '*', it will switch back
** to 1200 Baud. Hence I have to select the desired protocol
** first, then select the baud rate.
**
** The protocols supported by the (European) MouseMan are:
** - 5 byte packed binary protocol, as with the Mouse Systems
** mouse. Selected by sequence "*U".
** - 2 button 3 byte MicroSoft compatible protocol. Selected
** by sequence "*V".
** - 3 button 3+1 byte MicroSoft compatible protocol (default).
** Selected by sequence "*X".
**
** The following baud rates are supported:
** - 1200 Baud (default). Selected by sequence "*n".
** - 9600 Baud. Selected by sequence "*q".
**
** Selecting a sample rate is no longer supported with the MouseMan!
** Some additional lines in xf86Config.c take care of ill configured
** baud rates and sample rates. (The user will get an error.)
