=======================================================================
      Serial Mouse Does Not Work in OS/2 2.1 but IRQs Are Correct
=======================================================================

--------------------------------------------------------------

DESCRIPTION

The IRQs are correct, but the serial mouse does not work.

RESOLUTION

* COM3 or COM4 cannot support a serial mouse or pointing device.

* If the mouse is attached to COM1 or COM2, make sure the COM port is
  at the standard address and IRQ.

* On an ISA-bus (or AT-bus) system, a serial mouse can be installed
  only on COM1 or COM2, and only if COM1 and COM2 are at the standard
  I/O addresses and IRQs, which are:

  - COM1: 3F8, IRQ4
  - COM2: 2F8, IRQ3

* From an OS/2 or DOS command prompt, type MODE COMx and press Enter
  (where x is 1 or 2). This tests the COM ports.

  If the test reports that the port the mouse is attached to is not
  available, MOUSE.SYS is loaded. The drivers are correct.

  If the test reports the baud rate and all other COM-port parameters,
  MOUSE.SYS did not recognize the mouse and did not load. Edit the
  CONFIG.SYS file and check the MOUSE statement. The most-common
  statement is:

     DEVICE=C:\OS2\MOUSE.SYS

  Some older Logitech devices (for example, Trackman) are not
  detectable by MOUSE.SYS; however, they are still supported.

  The CONFIG.SYS statements for undetectable Logitech devices and PC
  Mouse System devices are:

     DEVICE=C:\OS2\PCLOGIC.SYS SERIAL=COM1
     DEVICE=C:\OS2\MOUSE.SYS TYPE=PCLOGIC$

  If the device is connected to COM2, change the SERIAL=parameter to
  COM2.

  Note: On an ISA-bus system, a serial mouse can be installed only on
        COM1 or COM2, and only if COM1 and COM2 are at the standard I/O
        addresses and IRQs, which are:

        * COM1: 3F8, IRQ4
        * COM2: 2F8, IRQ3

The following pointing devices were tested and verified to work.
Included are the CONFIG.SYS statements for each entry.

------                            ---------------------
IBM PS/2 Mouse                    DEVICE=C:\OS2\MOUSE.SYS

MS PS/2 Mouse                     DEVICE=C:\OS2\MOUSE.SYS

MS Serial Mouse                   DEVICE=C:\OS2\MOUSE.SYS

Kensington Expert PS/2 Mouse      DEVICE=C:\OS2\MOUSE.SYS
(Note: This is not the same as
 the Kensington serial mouse)

Logitech PS/2 Mouse               DEVICE=C:\OS2\MOUSE.SYS

MS Bus Mouse                      DEVICE=C:\OS2\MOUSE.SYS
(Note: This mouse requires a
 special card that works
 only on an ISA-style bus.)

MS Inport Mouse                   DEVICE=C:\OS2\MOUSE.SYS
(Note: This mouse requires a
 special card that works
 only on an ISA-style bus.)

Logitech Serial Mouse (Series M)  DEVICE=C:\OS2\MOUSE.SYS

Logitech Serial Mouse (Series C)  DEVICE=C:\OS2\PCLOGIC.SYS SERIAL=COM1
                                  DEVICE=C:\OS2\MOUSE.SYS TYPE=PCLOGIC$

Logitech Trackman serial mouse    DEVICE=C:\OS2\PCLOGIC.SYS SERIAL=COM2
                                  DEVICE=C:\OS2\MOUSE.SYS TYPE=PCLOGIC$

PC Mouse Systems serial mouse     DEVICE=C:\OS2\PCLOGIC.SYS SERIAL=COM2
                                  DEVICE=C:\OS2\MOUSE.SYS TYPE=PCLOGIC$

PC Mouse Systems bus mouse        DEVICE=C:\OS2\MSBUS01.SYS
                                  DEVICE=C:\OS2\MOUSE.SYS TYPE=MSBUS$

Visi-On serial mouse              DEVICE=C:\OS2\PCLOGIC.SYS SERIAL=COM2
                                  DEVICE=C:\OS2\MOUSE.SYS TYPE=PCLOGIC$

Note: Hundreds of pointing devices are available, and most are
      Microsoft-compatible. If they are 100% Microsoft-compatible,
      they are supported with the following CONFIG.SYS statement:

         DEVICE=C:\OS2\MOUSE.SYS.

      Devices that are not 100% compatible are not supported.
