### Monitoring Port Status

Use this procedure to monitor the status of a RealPort port.

#### Notes

- When monitoring ports, you can change the port monitoring delay by using the sliding scale along the bottom of the Ports window.
- Modem signal values are only correct for open ports. Ports in the closed or waiting state may not display the correct modem signals.
- When monitoring ports, the Refresh button may be selected at any time to update the port fields.

#### Procedure

1. Access Digi RealPort Manager by entering this command at a Linux prompt:

   `/usr/bin/dgrp/config/dgrp_gui`

   Note: Digi will only support use of the GUI with the wish interpreter. The wish tcl interpreter needs to be in the Linux "path" before the dgrp_gui command will work.

2. Choose the appropriate Digi device in the list box.
3. Choose the Ports option of the View menu.
4. Choose the appropriate port in the Ports Window.
5. Press either the Modem Status button or select the Modem Status option of the Ports menu. The Port Status window will appear. A signal will show a red box if it is active or a gray box if it is inactive.

#### Ports Window Information

These are the fields of the Ports Window:

Field | Description
Port | Port is the port number of an individual port. The first port on a Digi One RealPort or PortServer is port number 0.
Status | The value of this field is either open, closed, or waiting. A port moves into the waiting state when there are devices waiting to open the port (either waiting for an event, or for another process to release the port).
Speed | This value is the last known speed (in bps) of the port. If unknown (for instance, before the port is used for the first time), the value 0 is shown.
Description | This field is not yet active and will always show NA
