[pure virtual]
bool
QModbusTcpConnectionObserver::
acceptNewConnection
(
QTcpSocket
*
newClient
)
This function is a callback for every incoming TCP connection. The user should provide newClient to receive a notification when a new client connection is established and to determine whether the connection is to be accepted.
The function should return
true
if the connection is to be accepted. Otherwise, the socket is closed/rejected.
