BEst way to write to serial port in this example

[etantonio]

In this class that I use to write to a serial port my problem is that
I want to recall the method sendCommand from the main but I don't know
the best way to arrange this,
I also don't know if it is right to leave empty the run method
Can someone explain how with this code I could write to the serial
port ??

Thanks,
