1407 ** The following lines take care of the Logitech MouseMan protocols.
1409 ** NOTE: There are different versions of both MouseMan and TrackMan!
1410 ** Hence I add another protocol P_LOGIMAN, which the user can
1411 ** specify as MouseMan in his XF86Config file. This entry was
1412 ** formerly handled as a special case of P_MS. However, people
1413 ** who don't have the middle button problem, can still specify
1414 ** Microsoft and use P_MS.
1416 ** By default, these mice should use a 3 byte Microsoft protocol
1417 ** plus a 4th byte for the middle button. However, the mouse might
1418 ** have switched to a different protocol before we use it, so I send
1419 ** the proper sequence just in case.
1421 ** NOTE: - all commands to (at least the European) MouseMan have to
1422 ** be sent at 1200 Baud.
1423 ** - each command starts with a '*'.
1424 ** - whenever the MouseMan receives a '*', it will switch back

1743 * We have already processed the standard packet with the movement
1744 * and button info. Now post an event message with the old status
1745 * of the left and right buttons and the updated middle button.
1749 * Even worse, different MouseMen and TrackMen differ in the 4th
