- The information in this article applies to:
-
- - Microsoft Windows NT operating system, version 3.1

- WARNING: Using Registry Editor incorrectly can cause
- serious, system-wide problems that may require you to
- reinstall Windows NT to correct them. Microsoft cannot
- guarantee that any problems resulting from the use of
- Registry Editor can be solved. Use this tool at your own
- risk.
-
- Microsoft Windows NT and Windows NT Advanced Server support up to 256
- COM ports on each workstation. Use the Ports application in the
- Windows NT Control Panel to add ports. However, Windows NT does not
- provide a graphical interface to remove ports after adding them. To
- remove a COM port, you must use the Registry Editor utility.
-
- Perform the following five steps to remove a COM port from a Windows
- NT or Windows NT Advanced Server workstation:
-
- 1. Start the Registry Editor (REGEDT32.EXE)
-
- 2. Find the following key:
-
- \HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services
- \Serial\Parameters
-
- 3. The Parameters key has several subkeys such as Serial10000,
- Serial10001, and so on. Each of these subkeys corresponds to a COM
- port. To determine the COM port to which each applies, check the
- corresponding DosDevices value.
-
- 4. After you determine the COM port to remove, choose the appropriate
- Serial<xxxxx> subkey and choose Delete from the Edit menu.
-
- 5. Close the Registry Editor and shutdown and restart your system.
