1622 ********************************************************************
1623 **
1624 ** The following lines take care of the Logitech MouseMan protocols.
1625 **
1626 ** NOTE: There are different versions of both MouseMan and TrackMan!
1627 ** Hence I add another protocol P_LOGIMAN, which the user can
1628 ** specify as MouseMan in his XF86Config file. This entry was
1629 ** formerly handled as a special case of P_MS. However, people
1630 ** who don't have the middle button problem, can still specify
1631 ** Microsoft and use P_MS.
1632 **
1633 ** By default, these mice should use a 3 byte Microsoft protocol
1634 ** plus a 4th byte for the middle button. However, the mouse might
1635 ** have switched to a different protocol before we use it, so I send
1636 ** the proper sequence just in case.
1637 **
1638 ** NOTE: - all commands to (at least the European) MouseMan have to
1639 ** be sent at 1200 Baud.
1640 ** - each command starts with a '*'.
1641 ** - whenever the MouseMan receives a '*', it will switch back
1642 ** to 1200 Baud. Hence I have to select the desired protocol
1643 ** first, then select the baud rate.
1644 **
1645 ** The protocols supported by the (European) MouseMan are:
1646 ** - 5 byte packed binary protocol, as with the Mouse Systems
1647 ** mouse. Selected by sequence "*U".
1648 ** - 2 button 3 byte MicroSoft compatible protocol. Selected
1649 ** by sequence "*V".
1650 ** - 3 button 3+1 byte MicroSoft compatible protocol (default).
1651 ** Selected by sequence "*X".
1652 **
1653 ** The following baud rates are supported:
1654 ** - 1200 Baud (default). Selected by sequence "*n".
1655 ** - 9600 Baud. Selected by sequence "*q".
1656 **
1657 ** Selecting a sample rate is no longer supported with the MouseMan!
1658 ** Some additional lines in xf86Config.c take care of ill configured
1659 ** baud rates and sample rates. (The user will get an error.)

3205 * code to read from the Genius Kidspad tablet.
3206
3207The tablet responds to the COM PnP protocol 1.0 with EISA-ID KYE0005,
3208and to pre-pnp probes (RTS toggle) with 'T' (tablet ?)
32099600, 8 bit, parity odd.
3210
3211The tablet puts out 5 bytes. b0 (mask 0xb8, value 0xb8) contains
3212the proximity, tip and button info:
3213 (byte0 & 0x1) true = tip pressed
3214 (byte0 & 0x2) true = button pressed
3215 (byte0 & 0x40) false = pen in proximity of tablet.
3216
3217The next 4 bytes are used for coordinates xl, xh, yl, yh (7 bits valid).
3218
3219Only absolute coordinates are returned, so we use the following approach:
3220we store the last coordinates sent when the pen went out of the tablet,

1619 **
1620 ** The following lines take care of the Logitech MouseMan protocols.
1621 **
1622 ** NOTE: There are different versions of both MouseMan and TrackMan!
1623 ** Hence I add another protocol P_LOGIMAN, which the user can
1624 ** specify as MouseMan in his XF86Config file. This entry was
1625 ** formerly handled as a special case of P_MS. However, people
1626 ** who don't have the middle button problem, can still specify
1627 ** Microsoft and use P_MS.
1628 **
1629 ** By default, these mice should use a 3 byte Microsoft protocol
1630 ** plus a 4th byte for the middle button. However, the mouse might
1631 ** have switched to a different protocol before we use it, so I send
1632 ** the proper sequence just in case.
1633 **
1634 ** NOTE: - all commands to (at least the European) MouseMan have to
1635 ** be sent at 1200 Baud.
1636 ** - each command starts with a '*'.
1637 ** - whenever the MouseMan receives a '*', it will switch back
1638 ** to 1200 Baud. Hence I have to select the desired protocol
1639 ** first, then select the baud rate.
1640 **
1641 ** The protocols supported by the (European) MouseMan are:
1642 ** - 5 byte packed binary protocol, as with the Mouse Systems
1643 ** mouse. Selected by sequence "*U".
1644 ** - 2 button 3 byte MicroSoft compatible protocol. Selected
1645 ** by sequence "*V".
1646 ** - 3 button 3+1 byte MicroSoft compatible protocol (default).
1647 ** Selected by sequence "*X".
1648 **
1649 ** The following baud rates are supported:
1650 ** - 1200 Baud (default). Selected by sequence "*n".
1651 ** - 9600 Baud. Selected by sequence "*q".
1652 **
1653 ** Selecting a sample rate is no longer supported with the MouseMan!
1654 ** Some additional lines in xf86Config.c take care of ill configured
1655 ** baud rates and sample rates. (The user will get an error.)

3200/*
3201 * code to read from the Genius Kidspad tablet.
3202
3203The tablet responds to the COM PnP protocol 1.0 with EISA-ID KYE0005,
3204and to pre-pnp probes (RTS toggle) with 'T' (tablet ?)
32059600, 8 bit, parity odd.
3206
3207The tablet puts out 5 bytes. b0 (mask 0xb8, value 0xb8) contains
3208the proximity, tip and button info:
3209 (byte0 & 0x1) true = tip pressed
3210 (byte0 & 0x2) true = button pressed
3211 (byte0 & 0x40) false = pen in proximity of tablet.
3212
3213The next 4 bytes are used for coordinates xl, xh, yl, yh (7 bits valid).
3214
3215Only absolute coordinates are returned, so we use the following approach:
3216we store the last coordinates sent when the pen went out of the tablet,
