/drainuntilrestart |
Disables logons from new client sessions until the computer is restarted, but allows reconnections to existing sessions. |
/? |
Displays help at the command prompt. |
Remarks |
Logons are re-enabled when you restart the system. |
If you're connected to the Remote Desktop Session Host server from a client session, and then you disable logons and log off before re-enabling logons, you won't be able to reconnect to your session. To re-enable logons from client sessions, log on at the console. |
Examples |
To display the current logon status, type: |
change logon /query |
To enable logons from client sessions, type: |
change logon /enable |
To disable client logons, type: |
change logon /disable |

Parameters |
Parameter |
Description |
<portX>=<portY> |
Maps COM <portX> to <portY> |
/d <portX> |
Deletes the mapping for COM <portX> |
/query |

/? |

<portX> |
<portY> |
<portX> |
<portY> |
<portX> |
<portX> |
Remarks |
Most MS-DOS applications support only COM1 through COM4 serial ports. The change port command maps a serial port to a different port number, allowing apps that don't support high-numbered COM ports to access the serial port. Remapping works only for the current session and is not retained if you log off from a session and then log on again. |
Use change port without any parameters to display the available COM ports and their current mappings. |
Examples |
To map COM12 to COM1 for use by an MS-DOS-based application, type: |
change port com12=com1 |
To display the current port mappings, type: |
change port /query |
