If I want to give an command outside world through the serail port but do not care the response of it, do I need to poll or detect the event happen in the port? Moreover, for output only, is it true that I only need to open the port and put the output to the port only. But do I need to setup the port, such as the baud rate, the data bits, start, stop bits, and etc.?
Thank you!
