The DialOut/EZ Control Panel

  • DialOut/EZ virtual COM ports appear in the list.  Selecting a port shows its current settings.
  • Settings automatically become effective a few seconds after they are changed.
  • User Credentials are used only if the serial server requires a login.
  • The Connection Protocol and COM Port Options settings can be manually configured but typically they are set by the Configuration Wizard.
  • The Select Ports button lets you add or remove virtual COM ports.


Selecting Virtual COM Ports

  • The Select Ports window shows a list of COM ports (in the range of COM1 through COM4096). This list omits COM ports that are already used by other Windows device drivers.
  • DialOut/EZ creates a virtual COM port for each of the COM ports that you select.
  • If you deselect COM ports, DialOut/EZ removes the corresponding virtual COM ports.

The Configuration Wizard

  • When you add a new virtual COM port or use a serial server for the first time, the Configuration Wizard helps determine the correct settings.
  • You fill in the IP address and port number (and if needed, the username and password credentials) and the Wizard does the rest.
  • When you click the Start button, the Wizard interacts with the server to determine optimal settings for the current virtual COM port.
  • In this example, the serial server function is being done by the TacServe COM Port Server running on a PC, though any other modem server could be used.
  • When the Wizard completes, you can click the Use Settings button to transfer the Wizard's results to the settings in the DialOut/EZ Control Panel.

DialOut/EZ Port Monitor Activity Display

  • Right-click the system tray icon and select Port Monitor to see a real-time display in the Activity tab.
  • This example shows that COM4 (a DialOut/EZ virtual COM port) is being used and is connected to a serial server at
  • The disabled state of the CD (Carrier Detect) indicator shows that the modem (on the modem server) does not currently have a modem connection.

DialOut/EZ Port Monitor Trace Display

  • The Trace tab in the Port Monitor shows all activity on virtual COM ports.
  • Trace Options allow you to select the COM ports to be traced and optionally copy trace data to the Windows debug channel.
  • Trace data can be saved to a file for later analysis.
  • This example shows an 'atdt' modem command being entered on COM4.
