3-button mice and clearing dtr

[rob]

The best way to adjust if your mouse at work is a Sun optical mouse is to replace
the mouse at work.  Logitech, and I'm sure others, make Sun-compatible mice 
that don't hurt your hand.

3-button mice and clearing dtr

[Steve_Kilbane]

On the subject of mice in general, does anyone make an
optical mouse for PCs? Being used to a Sun at work means
that whenever I'm trying to B2-click on a command (in
Wily, as it happens), the button-press moves my home mouse
slightly, resulting in a non-null selection.

An even simpler way to initialise a dtr-switchable mouse is to replace the
aux/mouse command in /bin/termrc with

  { echo serial$mouseport >'#b/mousectl'; echo d0 } >/dev/eia$mouseport^ctl

The bad news is that this causes the kernel to panic.  (Don't try this at home.)

The good news is that the panic can be averted by a one-line change to
uartspecial() in /sys/src/9/pc/devuart.c:

602c602
<	up->oq = oq;
---
>	if (oq) up->oq = oq;

Been there, done that. I added uartdtrmouse() in place of
uartspecial(), added a message to tell aux/mouse it's a dtr
mouse and ripped the guts out of aux/mouse so it doesn't
faf around trying to work out what sort of mouse it's got.

If anyone's interested, I can wrap it up and send it as
a Christmas pressie to 9fans.

	You an also adopt the bloody, hardware-based solution :-)

3-button mice and clearing dtr

[miller]

If your mouse is like mine, and reverts to 2-button behaviour
if dtr is reasserted, you'll find that the suggestion from
forsyth@plan9.cs.york.ac.uk:

> change aux/mouse.c
>
> add a timedwrite(ctl, "d0", 2)

doesn't do the trick.  aux/mouse finishes by writing a "serial ..."
command to /dev/mousectl, which causes the kernel to raise dtr
and then lock the serial port so it can't be changed again.

A sensible solution would probably require adding a new parameter
to aux/mouse, and to routines serialmouse() and uartspecial() in the
kernel.  Or buying a proper three-button mouse.

A quicker and dirtier way is:

1. Insert at the end of uartspecial() in /sys/src/9/pc/devuart.c:
		{ char *p;
		  if (iq == &mouseq && (p = getconf("mousedtr")))
			uartdtr(up, strtoul(p, 0, 0));
		}
   and rebuild the kernel.

2. Insert into the plan9.ini configuration file the line
		mousedtr=0

3. In the /bin/termrc shell script, replace the line
		aux/mouse $mouseport
   with
		echo serial$mouseport >'#b/mousectl'

This works for me.

[forsyth]

change aux/mouse.c

add a timedwrite(ctl, "d0", 2)
in a suitable place; possibly at the start of C() if the mouse
keeps to that setup protocol; alternatively, before setting up
the default using -dC.

my mouse requires that dtr be clear to operate as a three button mouse.
it then uses the mouse systems protocol.

how can i get to work properly with my standalone pc plan9?

many thanks
