### Uninstalling RealPort

Use this procedure to uninstall the AIX RealPort driver.

Note: Before uninstalling the RealPort driver, users in most instances should remove the TTY devices and the Digi RealPort device. Not removing the devices leaves files in the system's object database.

#### Procedure

1. Log onto the system as superuser (root).
2. Disable login on any RealPort TTY device with a login enabled on it.
3. Kill any processes open on any RealPort TTY or lp device.
4. Determine the Digi device sa device(s). At the command prompt, enter:

`smit devices`

and choose Digi Ethernet-based Serial Device.

5. Use the rmdev command to remove all the RealPort sa TTY, and lp devices.

   `rmdev -l [sa device] -R -d`

   Note: The -R option, when used to remove an sa device, will delete the sa device specified and all the TTY and lp devices assigned to it. This is useful if there are many RealPort devices to remove from the system. If you wish to remove individual TTY and lp devices with the rmdev command, the -R option should not be used.

6. Enter the command:

`smit install_remove`

A dialog panel appears.

7. Alter the field SOFTWARE name to:

`digiasync.ncxa.obj`

8. Alter the field PREVIEW only to:

`no`

9. Choose OK.

   This prompt appears: Are You Sure?

10. Choose OK.

    The uninstallation should proceed to a successful conclusion.
