[SOLVED] Serial Port Bug?: Double display of input in Terminal Example | SOLVED

[Sen Li]

I am a beginner of QSerialPort, and learning the Terminal Example, try to communicate with an optical sensor.

I use that example to talk to the sensor, try to send string to it, however, whenever I type any one letter into the console, it shows up two letter, what's happening?

It works like below:

ACTIONS MENU:
(1) Send command string
(2) Send ASCII characters
(3) Continuous receive
(4) Return to main menu

->11

Enter hex string of 256 values or less. Press return when finished.
RR = Receive, CH = Chip Select High, CL = Chip Select Low, DY = 10ms Delay
RRRR
R1 = 0x00
String sent!

Actually I just typed in "1" and "RR", it shows like I typed in as "11" and "RRRR".

Has anyone encountered this problem?
How should I fix this?
Thank you!

If you are using the terminal example provided by Qt then under settings there is "Local echo". Uncheck that.

Settings is under the gear icon.
