1396 ********************************************************************
1398 ** The following lines take care of the Logitech MouseMan protocols.
1400 ** NOTE: There are different versions of both MouseMan and TrackMan!
1401 ** Hence I add another protocol P_LOGIMAN, which the user can
1402 ** specify as MouseMan in his XF86Config file. This entry was
1403 ** formerly handled as a special case of P_MS. However, people
1404 ** who don't have the middle button problem, can still specify
1405 ** Microsoft and use P_MS.
1407 ** By default, these mice should use a 3 byte Microsoft protocol
1408 ** plus a 4th byte for the middle button. However, the mouse might
1409 ** have switched to a different protocol before we use it, so I send
1410 ** the proper sequence just in case.
1412 ** NOTE: - all commands to (at least the European) MouseMan have to
1413 ** be sent at 1200 Baud.
1414 ** - each command starts with a '*'.
1415 ** - whenever the MouseMan receives a '*', it will switch back
1416 ** to 1200 Baud. Hence I have to select the desired protocol
1417 ** first, then select the baud rate.
1419 ** The protocols supported by the (European) MouseMan are:
1420 ** - 5 byte packed binary protocol, as with the Mouse Systems
1421 ** mouse. Selected by sequence "*U".
1422 ** - 2 button 3 byte MicroSoft compatible protocol. Selected
1423 ** by sequence "*V".
1424 ** - 3 button 3+1 byte MicroSoft compatible protocol (default).

1734 * We have already processed the standard packet with the movement
1735 * and button info. Now post an event message with the old status
1736 * of the left and right buttons and the updated middle button.
1740 * Even worse, different MouseMen and TrackMen differ in the 4th

1748 * to be extended so that it is identified as Button 4. The lower
1749 * half of the reverse-map may remain unchanged.

1755 * been detected (pBufP >= cur_proto[4]). In the previous
