DOCUMENT:Q167394 25-FEB-2002 [winnt] TITLE :Installed Modem Detected as Serial Mouse on Restart PRODUCT :Microsoft Windows NT PROD/VER::4.0 OPER/SYS: KEYWORDS:kbsetup ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 4.0 - Microsoft Windows NT Server version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== During the setup of Remote Access Service (RAS) on a Windows NT 4.0 server computer, a serial modem is installed and configured. When the server is restarted, the modem is detected as Microsoft Serial Mouse and the modem is no longer usable by RAS. CAUSE ===== During startup of Windows NT, the NTDETECT program gathers information about the hardware installed on the system including pointing devices such as serial mice. If a mouse is detected, the system designates that port as a mouse port and does not allow it to be used for other purposes, such as a modem. Data is sent to the serial ports and the response from the modem is interpreted as the presence of a mouse. The system will attempt to load serial mouse software for that com port and prevent the use of the port for serial modems. RESOLUTION ========== Edit the boot.ini file and add to the end of the "Operating Systems" lines one of the following; /NoSerialMice (This disables detection of Serial Mice on all COM ports -or- /NoSerialMice:COMx (This disables detection of Serial Mice on only the COM port specified by x) For additional information, please see the following Microsoft Knowledge Base article: ARTICLE-ID: Q131976 TITLE : How to Disable Detection of Devices on Serial Ports Additional query words: ====================================================================== Keywords : kbsetup Technology : kbWinNTsearch kbWinNTWsearch kbWinNTW400 kbWinNTW400search kbWinNT400search kbWinNTSsearch kbWinNTS400search kbWinNTS400 Version : :4.0 Issue type : kbprb ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
