Troubleshooting SentryII for Windows NT
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.
What occurs in this instance is that the NT DETECT process at startup sends a signal to each com port to check for the presence of a serial mouse . This is recognizing the UPS attached to the com port as a serial mouse , which in turn then changes the resource of the com port from serial to sermouse . In order to prevent this from happening it is necessary to disable the NT DETEC signal on the port assigned to the UPS.
Windows NT Event Viewer
You may find additional help in solving your problems with the Event Viewer.>The Event
Viewer is in the Administrative Tools folder.
The Event Viewer lists each occurring event. To
display a list of event log messages, select Applications under the Log
menu. To view more details for the event, double-click on the event. The Event
Detail dialog box displays the Date and Time of the Event,
and a brief description of the event under Source.

| When you start Sentry, communications cannot be established. |
Make sure the Sentry service (Windows NT and OS/2) is started.
Make sure the cable is plugged into the UPS and the Computer.
Make sure you have correctly identified the serial ports. You may have connected the cable to the wrong port. Ports may be mislabeled.
Make sure the serial port is enabled.
Make sure the port is operational. Perform another test on it, such as attaching a modem and attempting to dial out.
A conflict may occur with hardware devices or other software. |
Windows NT COM Ports
To disable the detection of devices on COM ports in Windows NT:
- Make a backup copy of the Boot.ini file.
- Remove the hidden, system, and read-only attributes from the Boot.ini file.
- Using a text editor (such as Notepad) open the Boot.ini file.
- 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.
- Save Boot.ini and quit Notepad.
- Restore the hidden, system, and read-only attributes to the Boot.ini file.
- 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.
