If the file contains binary data, it can have a byte with any value including a line feed character.

after finding serial ports and connecting to it, m making a file output stream for serial port.n passing ma hex file name to outputstream.

What is the name of the class you are using to write to the serial port with?
Does it have methods for writing bytes?

name of the class is outputstream and it has a write method which take argument of byte 2 b written on serial port

What is 2 b?
Please use English.

There is no Java SE class: outputstream. Java is case sensitive and all classes start with a uppercase letter.

yes..OutputStream is the class name..and sorry for using shortcut language. :P hey Norm can you give me a simple code to send bytes from a file to serial port?

Can you explain what the problem is when you write the contents of a file? Your descriptions have been vague.
Post the code you are using to write the file and the code you are using to read the file.
