Statistics & Logs
The Modem Connections group of menus contains Connections, Connection Details, Caller Id and Call History
screens. The Connections, Connection Details and Caller ID screens provide various details about the current
state of each modem in the system. The Call History screen maintains a record of all calls that establish
carrier.
The Connections screen displays the state of each port, how it's allocated, who is using it and the start time
and duration of the current call.
The Port is a combination of serial tty and modem resource. The State column reflects three aspects; the port's
availability as a resource to the Linux system, the status of the modem and the modem's usage configuration.
The usage directly effects the state of the port. The state of "idle" means the port, as a system resource, is
available to the system and currently is not in use.
The state of "allocated" means as a system resource, it is being used. When the modem's usage is set to RAS
or FAX, the state of the port is "Allocated". When a successful call is established, the state will change from
Allocated to Data. When the call is finished, the state will return to Allocated.
When the modem's usage is set to one of the Modem Sharing options, the state of the port is "Idle". When the
TCP socket to the modem is successfully opened by a network based application, the state will change to
Allocated. When the network based application makes the modem dial or answer and if successful, the state
will change to Data. When the call is finished the state will return to allocated. When the application closes the
socket, the state will return to Idle.
The Data state is achieved via successful call progress negotiations. The following is a list of all possible
states.
