3.5.2 STARTDT & STOPDT
STARTDT (Start Data Transfer) and STOPDT (Stop Data Transfer) are used by the
client to control the data transfer from the 104S gateway. When the connection is
established, user data is not automatically enabled in the server until it receives a
STARTDT act request from the client. The server should respond with a STARTDT
con response to acknowledge the client request. Once this procedure is concluded,
the server can send monitor data to the client.
The client can interrupt the monitor data flow at any time sending a STOPDT act
command to the server.
