A voltmeter won't tell you much about the quality of the signal, High/Low voltage levels or what data exactly is being sent/received. At most it will tell you if something IS happening or not.Hi,
I want to check data is sent through comm port without oscilloscope.Now i only have voltmeter.How can i measure the voltage is in TX and RX of comm port at 9600 bps?
sure you can but reading will be meaninglessCan I use volmeter to measure voltage of signal at 9600 baud rate?
