Port States

Ports may be enabled or disabled depending on the state of the port monitor that controls them.

State		Notes
Serial (`ttymon`) Port States
	`Enabled`	The `ttymon` port monitor sends a prompt message to the port and provides login service to it.
	`Disabled`	Default state of all ports if `ttymon` is killed or disabled. If you specify this state, `ttymon` will send out the `disabled` message when it receives a connection request.
Network (`listen`) Port States
	`Enabled`	The `listen` port monitor scans the network for service requests and invokes services in response to those requests.
	`Disabled`	If the `listen` port monitor is killed or disabled, the ports it controls are automatically disabled. If you specify this state, `listen` will send out the `Disabled` message when it receives a connection request.
