                            throws IOException

Specified by:

openInputStream in interface javax.microedition.io.InputConnection

Throws:

IOException

openDataOutputStream

public DataOutputStream openDataOutputStream()
                                      throws IOException

Specified by:

openDataOutputStream in interface javax.microedition.io.OutputConnection

                              throws IOException

Specified by:

openOutputStream in interface javax.microedition.io.OutputConnection

Throws:

close

public void close()
           throws IOException

Specified by:

close in interface CommConnection

Specified by:

close in interface javax.microedition.io.Connection

Throws:

IOException

sendMessage

public void sendMessage(byte[] message)
                 throws EsfException,
                        IOException

Description copied from interface: CommConnection

Sends and array of bytes to a CommConnection

Specified by:

sendMessage in interface CommConnection

Parameters:

message - the array of bytes to send to the CommConnection

Throws:

EsfException

IOException

sendCommand

public byte[] sendCommand(byte[] command,
                          int timeout)
                   throws EsfException,
                          IOException

Description copied from interface: CommConnection

Sends and array of bytes to a CommConnection and returns an array of bytes that represents the 'response' to the command. If the timeout is exceeded before any bytes are read on the InputStream null is returned. This is meant to be used in common command/response type situations when communicating with serial devices

Specified by:

sendCommand in interface CommConnection

Parameters:

command - the array of bytes to send to the CommConnection

timeout - the maximum length of time to wait before returning a null response in the event no response is ever returned.

Returns:

an array of bytes representing the response

Throws:

EsfException

IOException

sendCommand

public byte[] sendCommand(byte[] command,
                          int timeout,
                          int demark)
                   throws EsfException,
                          IOException

Specified by:

sendCommand in interface CommConnection

Throws:

EsfException

IOException

flushSerialBuffer

public byte[] flushSerialBuffer()
                         throws EsfException,
                                IOException

Description copied from interface: CommConnection

Reads all bytes that are waiting in the serial port buffer and returns them in an array. This can be used to read unsolicited messages from an attached serial device.

Specified by:

flushSerialBuffer in interface CommConnection

Returns:

the array of bytes buffered on the InputStream if any

Throws:

EsfException

IOException
