RS 232 connected on ASC1 | Thales IoT Developer Community

I have connected one power meter on ASC1 port using RS 232. I write code below to connect meter and read data over using Modbus protocol.

String strCOM = "comm:COM1;baudrate=9600;bitsperchar=8;stopbits=1;parity=none;blocking=off;autocts=off;autorts=off";
commConn = (CommConnection);
inStream = commConn.openInputStream();
outStream = commConn.openOutputStream();
byte[] buffer = new byte[]{};

byte[] frame1 = "here Modbus request";
int available1 = inStream.available();
System.out.println("inStream Available : "+inStream.available());
readBytes =;
System.out.println("Read Integer : "+readBytes +" and Bytes size : "+buffer.length);

While I run application on ESH6 module then Always get response 0 byte.

so My question is how to know meter is connected on ASC1 or not? I mean there is any command to know ASC1 connected to meter.
I want to check my code to send request to meter or not. So I can figer out my code is wrong or module not request to meter.

I have read java_user_guide pdf file. I have write command AT^SCFG? but i can not understand response. see below response.
