BASE STATION OBJECT

6.2 METHODS

METHOD ALIVE

PURPOSE

Calls a base station.

DESCRIPTION

This method calls a base station to know if it is alive or not. When sending an alive

command to a base station present and operating in the network, it will answer with a

particular string. This command is totally asynchronous and managed through a

secondary thread which causes the STAR-Link™ ActiveX to answer with an event

called AliveEvent containing the base station string information.

If the Alive command is not right, the control sends an error event.
