java - Send byte array on serial port out put stream

Question

when I want to send byte array on serial port stream with java,on destination device I receive different result !!!

byte[] sendingPack = new byte[7];
    sendingPack[0] = 0x6E;
    sendingPack[1] = 0x55;
    sendingPack[2] = (byte) 0x0D;
    sendingPack[3] = (byte) (1 & 0x000000FF);
    sendingPack[4] = 0x01;
    sendingPack[5] = 0x0D; 
    sendingPack[6] = (byte) 0xAA;

    getSendBuffer().getOutputStream().write(sendingPack);

sending array : byte[]{0x6E,0x55,0x0D,0x01,0x01,0x0D,0xAA} 
receive result array : 6E 55 0D 0A 01 01 0D 0A AA 

on CodeVisionAVR terminal I receive "0A"!! how can I solve this problem??

Answer 1

The terminal is probably in text reading mode and not in binary read mode.

The 0x0A which is inserted after every 0x0D you send is a carriage return conversion.

The terminal converts " " to " ". It adds a line feed char to every carriage return.

The terminal converts every 0D to 0D 0A.

This same feature can be found in the ftp protocol. You tell your client how to transfer files: in text or binary mode.
