Removing a TTY

This procedure allows you to make a tty device unavailable and either keep its definition in the customized database or remove it from the database. To make a device unavailable is to unconfigure it. A tty device that is made unavailable but that has not been deleted from the database can be made available again with the same attributes. If the definition of the tty device has been deleted, the device cannot be made available again.

Prerequisites

1. A tty device must be defined to the system.
2. The tty must be disabled. Refer to the pdisable command.
