Enquire Link

EnquireLink is SMPP command that used to check communication between ESME and SMSC.

To enable this feature you need to set following property:

    _client.EnquireLinkInterval = TimeSpan.FromSeconds(30);     

EnquireLinkInterval defines a delay after last received PDU. It means that library won't send EnquireLink when early it receives any other PDU from remote side.
