1238 ** The following lines take care of the Logitech MouseMan protocols.
1240 ** NOTE: There are different versions of both MouseMan and TrackMan!
1241 ** Hence I add another protocol P_LOGIMAN, which the user can
1242 ** specify as MouseMan in his XF86Config file. This entry was
1243 ** formerly handled as a special case of P_MS. However, people
1244 ** who don't have the middle button problem, can still specify
1245 ** Microsoft and use P_MS.
1247 ** By default, these mice should use a 3 byte Microsoft protocol
1248 ** plus a 4th byte for the middle button. However, the mouse might
1249 ** have switched to a different protocol before we use it, so I send
1250 ** the proper sequence just in case.
1252 ** NOTE: - all commands to (at least the European) MouseMan have to
1253 ** be sent at 1200 Baud.
1254 ** - each command starts with a '*'.
1255 ** - whenever the MouseMan receives a '*', it will switch back
1256 ** to 1200 Baud. Hence I have to select the desired protocol
1257 ** first, then select the baud rate.
1259 ** The protocols supported by the (European) MouseMan are:
1260 ** - 5 byte packed binary protocol, as with the Mouse Systems
1261 ** mouse. Selected by sequence "*U".
1262 ** - 2 button 3 byte MicroSoft compatible protocol. Selected
1263 ** by sequence "*V".
1264 ** - 3 button 3+1 byte MicroSoft compatible protocol (default).
1265 ** Selected by sequence "*X".
1267 ** The following baud rates are supported:
1268 ** - 1200 Baud (default). Selected by sequence "*n".
1269 ** - 9600 Baud. Selected by sequence "*q".
1271 ** Selecting a sample rate is no longer supported with the MouseMan!

1542 * NOTE/2: On a PS/2 mouse any byte is valid as a data byte. Furthermore,
1543 * 0x80 is not valid as a header byte. For a PS/2 mouse we skip
1544 * checking data bytes.
1545 * For resyncing a PS/2 mouse we require the two most significant

1547 * and in case of an overflow we actually lose sync. Overflows
1548 * are very rare, however, and we quickly gain sync again after
1549 * an overflow condition. This is the best we can do. (Actually,

1571 * Microsoft 3 byte packet plus an optional 4th byte whenever the
1572 * middle button status changes.
1574 * We have already processed the standard packet with the movement
1575 * and button info. Now post an event message with the old status
1576 * of the left and right buttons and the updated middle button.
1580 * Even worse, different MouseMen and TrackMen differ in the 4th
1581 * byte: some will send 0x00/0x20, others 0x01/0x21, or even
1582 * 0x02/0x22, so I have to strip off the lower bits.
1585 * HACK for ALPS "fourth button". (It's bit 0x10 of the "fourth byte"
1586 * and it is activated by tapping the glidepad with the finger! 8^)
1587 * We map it to bit bit3, and the reverse map in xf86Events just has
1588 * to be extended so that it is identified as Button 4. The lower
1589 * half of the reverse-map may remain unchanged.
1594 * Receive the fourth byte only when preceding three bytes have
1595 * been detected (pBufP >= cur_proto[4]). In the previous
1596 * versions, the test was pBufP == 0; thus, we may have mistakingly
1597 * received a byte even if we didn't see anything preceding
