The lockout configuration dialog allows the configuration of calls, which are restricted from connecting to the node. Calls placed into the lockout list are stripped of any SSID. If a call connects with any SSID, and his no-SSID call is in the lockout list, the station will be disconnected receive a DM (disconnect message).
The logic of the Lockout can be reversed where the node will only allow connections from callsigns in the list. This feature allows sysops to operate a “members only” node.
