+Serial mouse reset
+------------------
+
+1: Set UART to 'break line' state (set bit 6 in the LCR).
+2: Clear the RTS and DTR (bits 0-1) in the MCR, wait a while.
+3: Set the RTS and DTR bits again.

+Serial mouse detection (identification bytes before optional PnP data)
+----------------------------------------------------------------------
+
+In Mouse Systems mode, mouse sends nothing.
+In Microsoft mode, mouse sends 'M' after dropping and raising RTS.
+In Logitech mode, mouse sends 'M3' after dropping and raising RTS.
+In wheel mode, mouse sends 'MZ@',0,0,0 after dropping and raising RTS.
+
+
+PS/2 pointing device ID (reported after 0F2h command)
+-----------------------------------------------------
+
+In standard mode, the device reports 0.
+In wheel mode, the device reports 3. This mode is enabled by sending a
+  Select Report Rate 200, a Rate 100 and finally a Rate 80 command sequence.
+In extended mode, the device reports 4. This mode is enabled by sending a
+  Select Report Rate 200, a Rate 200 and finally a Rate 80 command sequence.
