Problem with ASC1 on TC65i

[azm...@gmail.com]

Hi all! I have TC65i (Cinterion).
It is operated on DBS-mini developer board.
MES is ok.  My software works well.
One day I tried to use ASC1 serial port ("comm:com1").
I made the cable according to the datasheet. I use only GND, Rx, Tx. RTS and CTS are closed.
My device (MODBUS tool) is connected to ASC1 with this cable.
AT+IPR is set to 57600.

I have this code:

 String strCOM = "comm:com1;baudrate=57600";
 CommConnection commConn = (CommConnection)Connector.open(strCOM);
 InputStream inStream = commConn.openInputStream();
 OutputStream outStream = commConn.openOutputStream();
 
 outStream.write(arr);

So no exception is called during this code running.
So I mean the port com1 was opened and ARR was written to the buffer.
But the LEDs for ASC1 on developer board are not flashed and the MODBUS tool is silent.
So it means the ASC1 is not operated.

What's going on? And what can I do?

Also I know if the multipexer mode is switched on, then ASC1 is disabled.
But I didn't use multiplexer and I think it is disabled by default.

Please help me! )

Hello,

please, try this strCOM = "comm:COM1;baudrate=57600;autocts=off;autorts=off;blocking=off"

Thanks! I tried but no connection.

But now the ASC1' LED on the DevBoard is flashing when I send the data to port.
It means Rx and TX are active and device is connected.
But when I send MB packet there is only two zero bytes responses alltime.
MP packet is correct.
