OSMKSERM - SERIAL MOUSE DOES NOT WORK IN OS/2 2.1 BUT IRQS ARE CORRECT
01/30/96
=======================================================================
Serial Mouse Does Not Work in OS/2 2.1 but IRQs Are Correct
=======================================================================
Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------
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.
Device CONFIG.SYS Statements
------ ---------------------
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.
