$VER: SerMouse 2.20, serial mouse package (+driver) for PC mice.
Welcome to:
\ | /
- The ultimate PC-Mouse package -
/ | \
A lot of people don't like the standard Amiga mouse (and I don't blame 'm).
And if they do like him (I like to 'personalize' my mouse) he (she?) dies
within a short period of time. The market for specific Amiga mice is very
small. Most people like the PC mice and trackballs. I 'm using a PC mouse
of Q-tec, after my Amiga mouse died some years ago. To make it a bit easier
for people to use PC mice and trackballs on the Amiga, I decided to write
this packadge for the use of PC-mice on the Amiga. It contains the
following things (in this doc or the archive):
* A serial mouse driver for both Microsoft mice and Mouse System mice.
* A description for converting 9-pin Sub-D serial to 25-pin serial.
* A description for converting 9-pin Sub-D BUS-mouse to 9-pin Amiga
mouse.
* A description for converting 9-pin Mini-Din BUS-mouse to 9-pin Amiga
mouse.
The SerialMouse-driver
----------------------
The SerialMouse-driver is called "SerMouse" and should be included in this
package. It can only be used with Kickstart version 2.0 or above. The
current version is 2.20. You can start it from the command-line by typing
"SerMouse" or from the WorkBench by double-clicking on it's icon. To
deactivate it, just restart the program. If you want to activate it every
time your computer is switched on, add the command in your s:user-startup
or drag the icon to the WBStartup drawer (do not remove the DONOTWAIT
tooltype!).
You can specify the following things either as command-line argument or as
icon tooltype:
3BYTES or 5BYTES
This indicates the mouse-type you're using. 5BYTES is the default and most
used type. If you've got a 3-button mouse, it's deffenetely a 5BYTES type.
If the mouse doesn't work, just try the other type... I named the types
by the number of bytes they sent for one event.
DEVICE
The device to be used for reading serial data. Default is the
serial.device. SerMouse has been tested with the VECTOR Connection multi
I/O card and it worked without any problems.
UNIT
The device-unit to be used for reading serial data. Default is unit 0.
Also tested with the VECTOR board.
PRIORITY
This is the task-priority of the mouse-driver. The default is 20. This
should be OK. It's the same priority as the input.device eg. the standard
mouse.
The program SerMouse is (c) by me (K.P. van Beem) and is distributed as
FreeWare. This means, you may freely use and distribute it, as long as the
programm and this documentation is left unchanged. The source of the
programm is available as GiftWare. Contact me if you're interested in it.
It's partly C and partly assembler.
Be sure pin 22 of the serial-port is NOT connected to any line of the
mouse when you use a serial mouse. This will interfere with your parallel
port.
Converting 9-pin Sub-D serial to 25-pin serial
----------------------------------------------
Most serial mice do have a 9-pin Sub-D serial connector (that's the two-row
connector, NOT a din!). The Amiga has a 25-pin serial connector. In most
stores, you can by adapters from 9 to 25 pins. For those who want to build
them in stead of by them, or just want to connect a 25-pin connector
directly to the wire, this is how you should connect it (the pin-numbers
are normally written on the connectors):
9-pin 25-pin
D-Sub D-Sub
1 <==> 8 Carrier Detect
2 <==> 3 Recieve
3 <==> 2 Transmit
4 <==> 20 Data Terminal Ready
5 <==> 7 Signal Ground
6 <==> 6 Data Set Ready
7 <==> 4 Request To Send
8 <==> 5 Clear To Send
Do NOT connect pin 22 on the Amiga side (with pin 9 on the mouse side).
This will interfere with the parallel port of your Amiga. This line is the
Ring Indicator which is only used by modems (and most of the time not by
Amiga software).
And don't forget the shield-ground.
Converting 9-pin Sub-D BUS-mouse to 9-pin Amiga mouse
-----------------------------------------------------
Besides serial mice, there's an other type of mouse that is used for the
PC. Although not often these days. It's called the BUS-mouse. It's basicly
the same mouse as the Amiga (and the Atari) is using, but differently
wired. You can easily rewire the mouse (or make an adapter) and connect the
mouse on the mouse-port of the Amiga, just like you do with your standard
Amiga mouse. This way, you can use this type of mouse without a separate
driver. This is the way I use my PC mouse on the Amiga. You should rewire
the mouse as described below:
Amiga side Mouse side
D-Sub D-Sub
5 4 3 2 1 5 4 3 2 1
9 8 7 6 9 8 7 6
1 <==> 4 Vertical pulse
2 <==> 1 Horizontal pulse
3 <==> 3 Vertical pulse Qualifier
4 <==> 2 Horizontal pulse Qualifier
5 <==> 5 Midle button
6 <==> 6 Left button
7 <==> 7 +5V
8 <==> 8 Ground
9 <==> 9 Right button
Converting 9-pin Mini-Din BUS-mouse to 9-pin Amiga mouse
--------------------------------------------------------
For a description of the BUS mouse, see above. Besides the Sub-D plug, most
modern computers do have a mini-Din to connect the bus-mouse to the
computer. Of cause, these can also be rewired. Belose is described how. I
haven't tested this, but I took it from a German magazin.
Mouse Amiga
Mini-DIN D-SUB
1 <==> 7 +5V
2 <==> 2 Horizontal pulse
3 <==> 4 Horizontal pulse Qualifier
4 <==> 1 Vertical pulse
5 <==> 3 Vertical pulse Qualifier
6 <==> 6 Left button
7 <==> 5 Middle button
8 <==> 9 Right button
9 <==> 8 GND
I'm not sure the pin-nubers are written on the Mini-Din, besides, if you
don't make an adapter but just rewire it, you won't have the bus. So I'l
give the numbers here. You are looking at the soldier side of the bus, so
at the pin-side of the plug!

Changes since 2.00
------------------
* Added the warning in the docs about pin 22 (ring indicator). This pin
should NOT be connected. With some mice, it interacts with the printer
in such a way that you won't be able to print while the mouse in
connected.
* Some mouse-actions involving clicking with the mouse-buttons didn't work
as they should. This included console-clipping, drag-selecting in some
programs, double-click and other combinations in YAK and using PowerSnap.
This was partly coused by the input.device. It doesn't update the current
state of the buttons the way I tell it to do. In order to work around
this, I had to use some undocumented 'features' of the input.device. But
don't fear. It's proven to work safe on all OS versions released up till
now. Now the serialmouse-driver realy works as the 'normal' mouse!
Credits
-------
I want to thank the following people (in alphabetical order) who helped me
with this mice stuff:
Marcel Duyn, who lent me a serial mouse for testing the driver (correction
as for version 2.20: I now bought it :-)) )
Carsten Gerlach for finding out the couse of the serialmouse driver not
working with commodities like Yak and PowerSnap. (Myself for finding the
optimum solution :-)) )
Stefan Johannesdal, who tested the 5BYTES part of the driver.
Patrick Smith for letting me know some serial-mice do have pin 22 connected.
Christian Stieber, who provided me with some technical info about the
5BYTES serial mouse protocol.
For questions, suggestions or bug-reports, you can always reach me at the
adresses below.
Have fun! (Easy, 'cause you own an Amiga!)

Nice detail: The latest version of the Microsof mouse driver for windows I
installed on my PC consumed 1.6MB of harddisk space! I think I'll stick to
my Amiga :-))
