Configuring Socket Client For Calling A Socket Listener On Another Host; Socket Client Sends Data Via Tcp Connection (Polling Mode) - Multi-Tech MultiModem EDGE Reference Manual

10.14.3 Configuring Socket Client for Calling a Socket Listener on Another Host

The example assumes that a connection profile has been created as explained in Section 10.1.1 or Section 10.1.2.
Configure the client's service profile 1 for calling a Socket listener on another host:
at^siss=1,srvType,socket
OK
at^siss=1,conId,0
OK
at^siss=1,address,"socktcp://10.10.0.187:65534"
OK

10.14.4 Socket Client Sends Data via TCP Connection (Polling Mode)

The example uses service profile 0 configured for Socket service and TCP.
AT^SISO=0
OK
AT^SISI=0
^SISI: 0,3,0,0,0,0
OK
AT^SISI=0
^SISI: 0,4,0,0,0,0
OK
AT^SISW=0,10
^SISW: 0,10,10
0123456789
OK
AT^SISW=0,10,1
^SISW: 0,0,10
OK
AT^SISW=0,10,1
^SISW: 0,10,20
0123456789
OK
AT^SISW=0,0,0
^SISW: 0,0,10
OK
AT^SISI=0
^SISI: 0,5,0,20,10,10
OK
AT^SISI=0
^SISI: 0,6,0,20,20,0
OK
AT^SISC=0
OK

Chapter 10 – Internet Service Commands
Select service type Socket.
Select connection profile 0.
The service profile of the client contains the IP address and the TCP
port of the remote host.
The host opens service profile 0.
Note: URC ^SISW:0, 1 does not appear! The host must poll the service
state by means of AT^SISI until the service is in <srvState> "Up".
The service is still in <srvState> "Connecting".
The service is now in <srvState> "Up" and is ready to accept data.
The host requests to write 10 bytes.
Response that 10 bytes can be sent and are unacknowledged.
The host requests to write next 10 bytes and enables the end-of-data flag.
But the service refuses the request, even the end-of data flag remains
without effect.
Next try (polling).
Response that the service accepts 10 bytes and this data and the previously
sent data are unacknowledged.
Polling to request unacknowledged data.
There are 10 bytes still unacknowledged.
Polling for <srvState> change ("Closing" - Down>
20 bytes are transferred via serial interface, 10 bytes are acknowledged by
remote peer, 10 bytes are on the way.
Polling for <srvState> change ("Closing" -> "Down").
The Service is in state "Down" and all data is confirmed by the remote peer.
Closing the Socket service.
