[time-nuts] Oncore VP problem

The bouncing mouse is always a fun problem. If you go up to the Synergy at:

http://www.synergy-gps.com/images/stories/ShopTalk/disabling detection of
microsoft ballpoint mouse.pdf

there is an old paper I wrote about this problem. Disabling the mouse in the
Windows system folder works pretty well, but on more than one occasion I
have seen it mysteriously reappear. As you noted, this only happens when the
receiver is plugged in during a boot. If the receiver is plugged in during a
boot, unplugging it and plugging it back in will not help. Apparently this
is a system variable that is set during boot.

The second half of the paper is the registry fix that Rick Hambly showed me
several years ago. I think this method is included in his TAC32 user
manuals. This is the way to REALLY shut the serial mouse down for good.

Note that this problem is not limited to VP receivers. If you have anything
plugged into a serial port outputting data during boot that your computer
thinks is valid mouse data the same thing will happen.

My  suggestion is that you pick up a free evaluation copy of Rick
Hambly's  TAC32 software at http://cnssys.com/cnsclock/Tac32Software.html
. TAC32  knows all the quirks & options that ever existed in a  Motorola
receiver, going all the way back to the Rev.3 PVT6. Then if you  find it
useful, a legal copy can be purchased from Rick, or at members  discount
from TAPR  (http://www.tapr.org/gps_tac32.html).

Hi Tom
Many thanks for the suggestion.
You may have seen my subsequent post in which I commented that I had tried  
TAC32 without solving my problem, only to find the kit was working ok but
an incorrectly labelled connector.
TAC32 does look useful though so I'll check it over more thoroughly  later.
One "interesting" side effect......
Some time after shutting down TAC32 last night, but with the Oncore still  
connected to the serial port and outputting data, my PS2 connected mouse
 misbehaving, with the pointer jumping all over the place then settling down

for  a while before repeating the performance.
It didn't occur to me at first that the incoming serial data might have  
anything to do with it until it started again this morning and I eventually

stopped it by disconnecting the serial lead from the receiver.
Whilst I can't say for sure that running TAC32 was what caused it, it's not

something I've ever seen in the past nor previously this past few  days
running WinOncore.
I'll check later to see if the port shut down properly and also take a look

at the Oncore message stream, perhaps TAC32 may have changed something
as part of its auto setup routine?
