Method Detail

open

public static int open(java.lang.String deviceName)

Open the serial port by the specified device name.

Parameters:

deviceName - in WizarPOS1, deviceName is DB9, in WizarHANDQ1, deviceName is WIZARHANDQ1.

Returns:

value >= 0, success in starting the process; value < 0, error code

close

public static int close()

Close the serial port opened before.

Returns:

value >= 0, success in starting the process; value < 0, error code

read

public static int read(byte[] pDataBuffer,
                       int nExpectedDataLength,
                       int nTimeout_MS)

Get information from the serial port.

Parameters:

pDataBuffer - Data buffer

nExpectedDataLength - Data length to read

nTimeout_MS - Time in milliseconds. <0: read until got data.

Returns:

value >0, data length; value < 0, error code

write

public static int write(byte[] pDataBuffer,
                        int offset,
                        int nDataLength)

Send information from the serial port.

Parameters:

pDataBuffer - Data buffer

offset - offset of the data buffer

nDataLength - data length of write

Returns:

value >=0, write data length; value < 0, error code

setBaudrate

public static int setBaudrate(int nBaudrate)

Set the baud rate of the serial port so that this device can read and write in the same baud rate.

Parameters:

nBaudrate - baud rate

Returns:

value >=0, write data length; value < 0, error code

flushIO

public static int flushIO()

Flush the IO buffer of the serial port.

Returns:

value >=0, success; value < 0, error code

isOpened

public static boolean isOpened()

Recognize if the serial port is open.

Returns:

true is opened
