penable Command

Purpose

Enables or reports the availability of login ports.

Syntax

penable [ -a ] [ Device ]

Description

The penable command enables normal ports. Normal ports are asynchronous and only allow users to log in. No outgoing use of the port is allowed while it is enabled. The system enables a port by updating an entry in the /etc/inittab file and then sending a signal to the init process. After receiving the signal and reading the updated status entry, the process takes the appropriate action.

Use the Device parameter to specify the ports to be enabled. Permitted values include:

If you do not specify a Device parameter, the penable command reports the names of the currently enabled normal ports.

Note: You must have root user authority to run this command.

Flags

Example

To enable all normal ports listed in the /etc/inittab file, enter:

penable -a
