281 Microsoft IntelliMouse protocol. Genius NetMouse, ASCII Mie Mouse,
282 Logitech MouseMan+ and FirstMouse+ use this protocol too.
283 Other mice with a roller/wheel may be compatible with this protocol.
285 MouseSystems 5-byte protocol. 3-button mice may use this protocol.
287 MM Series mouse protocol.
289 Logitech mouse protocol. Note that this is for old Logitech models.
293 should be specified for newer models.
295 Logitech MouseMan and TrackMan protocol. Some 3-button mice may be compatible

314 .Bl -tag -compact -width mousesystemsxxx
316 This is the only protocol type available for
317 the bus and InPort mouse and should be specified for any bus mice
318 and InPort mice, regardless of the brand.

324 This is the only protocol type available for the PS/2 mouse

333 Make the physical button
335 act as the wheel mode button.

371 This is useful for the mouse with two wheels of which
372 the second wheel is used to generate horizontal scroll action,
373 and for the mouse which has a knob or a stick which can detect
374 the horizontal force applied by the user.

391 Note also that some mice think left is the negative horizontal direction,
392 others may think otherwise.
393 Moreover, there are some mice whose two wheels are both mounted vertically,
394 and the direction of the second vertical wheel does not match the
398 .Ss Configuring Mouse Daemon
399 The first thing you need to know is the interface type
400 of the mouse you are going to use.
401 It can be determined by looking at the connector of the mouse.
402 The serial mouse has a D-Sub female 9- or 25-pin connector.
403 The bus and InPort mice have either a D-Sub male 9-pin connector
404 or a round DIN 9-pin connector.
405 The PS/2 mouse is equipped with a small, round DIN 6-pin connector.
406 Some mice come with adapters with which the connector can
407 be converted to another. If you are to use such an adapter,
408 remember the connector at the very end of the mouse/adapter pair is
410 The USB mouse has a flat rectangular connector.
412 The next thing to decide is a port to use for the given interface.
413 For the bus, InPort and PS/2 mice, there is little choice:
414 the bus and InPort mice always use
416 and the PS/2 mouse is always at
418 There may be more than one serial port to which the serial
419 mouse can be attached. Many people often assign the first, built-in

428 You may want to create a symbolic link
430 pointing to the real port to which the mouse is connected, so that you
431 can easily distinguish which is your ``mouse'' port later.
433 The next step is to guess the appropriate protocol type for the mouse.

442 the protocol type, no further investigation is necessary on your part.

471 .Bl -enum -compact -width 1.X
473 The bus and InPort mice always use

497 3-button serial mice may also work with the
499 protocol under which the third button may function as expected.
501 3-button serial mice may have a small switch to choose between ``MS''
502 and ``PC'', or ``2'' and ``3''.
503 ``MS'' or ``2'' usually mean the
506 ``PC'' or ``3'' will choose the

515 To test if the selected protocol type is correct for the given mouse,
516 enable the mouse pointer in the current virtual console,
520 start the mouse daemon in the foreground mode,
522 .Dl moused -f -p Ar _selected_port_ -t Ar _selected_protocol_
524 and see if the mouse pointer travels correctly
525 according to the mouse movement.
526 Then try cut & paste features by
527 clicking the left, right and middle buttons.
531 As many instances of the mouse daemon as the number of mice attached to
532 the system may be run simultaneously; one
533 instance for each mouse.
534 This is useful if the user wants to use the built-in PS/2 pointing device
535 of a laptop computer while on the road, but wants to use a serial
536 mouse when s/he attaches the system to the docking station in the office.
537 Run two mouse daemons and tell the application program
539 .Tn "X\ Window System" )
542 then the application program will always see mouse data from either mice.
543 When the serial mouse is not attached, the corresponding mouse daemon
544 will not detect any movement or button state change and the application
545 program will only see mouse data coming from the daemon for the
547 In contrast when both mice are attached and both of them
548 are moved at the same time in this configuration,
549 the mouse pointer will travel across the screen just as if movement of

620 Many pad devices behave as if the first (left) button were pressed if
621 the user `taps' the surface of the pad.
622 In contrast, some ALPS GlidePoint and Interlink VersaPad models
623 treat the tapping action
624 as fourth button events.
625 Use the option ``-m 1=4'' for these models
626 to obtain the same effect as the other pad devices.
628 Cut and paste functions in the virtual console assume that there
629 are three buttons on the mouse.
630 The logical button 1 (logical left) selects a region of text in the
631 console and copies it to the cut buffer.
632 The logical button 3 (logical right) extends the selected region.
633 The logical button 2 (logical middle) pastes the selected text
634 at the text cursor position.
