my project neet to change these two attribute when in data communication. For example : port.setParameters(9600, 8, UsbSerialPort.STOPBITS_1, UsbSerialPort.PARITY_EVEN); ...write some data port.setParameters(9600, 8, UsbSerialPort.STOPBITS_2, UsbSerialPort.PARITY_NONE); ...write some data ...read bytes port.setParameters(9600, 8, UsbSerialPort.STOPBITS_1, UsbSerialPort.PARITY_EVEN); .....write some data ....read bytes

i wrote code like this ,but the result not working as expected. i want to ask how can i do that stopbit and PARITY can be changed in data communication.

parameters can be changed with setParameters repeatedly when the connection is open, e.g. tested here. maybe you have to wait until old data is fully read/written
