Resetting a Serial Port's RTS and DTR Signals when Windows Starts

de Joe W4TV

You can reset a serial port's RTS and DTR signals on Windows startup by creating a Windows Batch File containing the appropriate command, and then creating a Window Shortcut to this Batch File in the Windows Startup Folder. To reset COM3's RTS and DTR signals, for example, use Windows Notepad to create a Batch File named RESETCOM3.bat that contains

MODE COM3; dtr=off rts=off

On Windows XP, the pathname of the Windows Startup Folder is

C:\Documents and Settings\%username%\Start Menu\Programs\Startup

where %username% is the username you used to log in to Windows.

On Windows 7, the pathname of the Windows Startup Folder is

C:\users\%username%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

To create the required Shortcut, run two instances of Windows Explorer. In the first instance, navigate to the folder in which you created RESETCOM3.bat; in the second instance, navigate to the Windows Startup Folder. Then depress-and-hold the ALT key while dragging RESETCOM3.bat from the first instance of Windows Explorer to the second; when you release the left mouse button, a shortcut to RESETCOM3.bat will appear in the Windows Startup Folder.
