Help needed in serial port connection

Question

I tried to write a midlet such that an emulator can get images from a webcam which shall is attached to the serial port of a cell phone. But I always get the following error message:
IOException:javax.microedition.io.ConnectionNotFoundException: The requested protocol does not exist comm:0;baudrate=9600
My code appears as follows:
InputConnection cc;
DataInputStream inc;
static byte img_data[];
static int frame_len = 30000;
public void start()
try
System.out.println("I am here:");
cc = (StreamConnection)Connector.open("comm:0;baudrate=9600");
//************* I can't pass through here
//I also try to use
//cc = (StreamConnection)Connector.open
//("comm:0;baudrate=9600;bitsperchar=8;stopbits=1;parity=none");
// to do it, but get same problem
inc = new DataInputStream(cc.openDataInputStream());
inc.readFully( img_data);
catch (IOException e)
{   System.err.println("IOException:" + e);  }
finally
// free up the I/O stream after use
try { if (inc != null ) inc.close(); }
catch (IOException ignored) { System.err.println ("Exception:" + ignored); }
// free up the connection after use
try { if ( cc != null ) cc.close(); }
catch (IOException ignored) { System.err.println("Exception:" + ignored); }
System.out.println("I am ok:");
Does anybody know some reasons that probably lead to this error.
thanks in advance

Answer 1

well, as i know, midp 1.0 does not support serial connections, actually, any connection type other than http connection.
this is my problem noeadays too, is it practically possible to use serial connection under midp.
have you had any improvements since than?
