Dear Fred and J -
Here is some info which was forwarded to me by Bob Fulks. It might be a
more straightforward and safer way to solve the problem. I've made the
change to my boot.ini but I've not yet rebooted to test it out. I'll wait
till the weekend to do so.
In the following procedure, the COM which you must specify to the
"NoSerialMice" entry is that to which your BMI box is attached. Here's the
material:
How to Disable Detection of
Devices on Serial Ports
Article ID: Q131976
The information in this article applies to:
Microsoft Windows NT operating system version 3.1
Microsoft Windows NT Advanced Server version 3.1
Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0
Microsoft Windows NT Server versions 3.5, 3.51, 4.0
SUMMARY
This article explains how to modify the Boot.ini file to disable the
detection of devices on COM ports.
When you start Windows NT, NTDETECT searches for the pointing
device (usually a mouse). In the course of this process, data is sent to
the serial (COM) ports. If a serial mouse is detected, Windows NT
disables the port so a device driver for the mouse can load instead. If
a device is not detected, Windows NT disables the port. A disabled
COM port does not display any information in Control Panel Ports.
MORE INFORMATION
To disable the detection of devices on COM ports in Windows NT:
1.Make a backup copy of the Boot.ini file.
2.Remove the hidden, system, and read-only attributes from the
Boot.ini file.
3.Using a text editor (such as Notepad) open the Boot.ini file.
4.Add the /NoSerialMice option to the end of each entry in the
[operating systems] section of Boot.ini. See the example below
for more information.
5.Save Boot.ini and quit Notepad.
6.Restore the hidden, system, and read-only attributes to the
Boot.ini file.
7.Shutdown and restart Windows NT.
The following is a sample of the Boot.ini file:
[boot loader]
timeout=3
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT35
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT35="Windows NT Workstation
Version 3.51" /NoSerialMice
multi(0)disk(0)rdisk(0)partition(1)\WINNT35="Windows NT Workstation
Version 3.51 [VGA mode]" /basevideo /sos /NoSerialMice
NoSerialMice Syntax
/NoSerialMice - Disables the detection of serial mice on
all COM ports.
/NoSerialMice:COMx - Disables the detection of serial mice on
COM x, where x is the number of the port.
/NoSerialMice:COMx,y,z - Disables the detection of serial mice on
COM x, y and z.
NOTE: The /NoSerialMice option is not case sensitive.
