CLI Echo problem (using RRT with SDW) with nrf52832 based custom board

[Dhillon]

When I am using peripheral/cli example and debugging through RRT, I see following outcome when I am typing commands.

OUTPUT : 

Command Line Interface example started.

Please press the Tab key to see all available commands.

rtt_cli:~$ 

rtt_cli:~$ 

  app_size  balloc    clear     cli       counter   dynamic   error

  flashlog  history   log       log_msg   mpu       nordic    print

  python    queue     reset     resize

rtt_cli:~$ rrreeessseeettt

Question : Why I am seeing multiple echo when I type commands. I try to turn off echo but it help me reduce 3 times echo to 2 times echo (means when I type a character it echos 3 times but by turning off echo it echos 2 times) ?

I did not changed anything in example code.

I am using 

JLinkExe -device nRF52 -speed 4000 -if SWD on one terminal 

JLinkRTTClient on another terminal.

Thank you in advance.

Hi Edvin,

I missed to mention, I am not using windows. So I'm not able to use Putty. I'm using MacBook.

I followed - https://devzone.nordicsemi.com/f/nordic-q-a/8184/rtt-on-os-x this (answered by Karlsen).

Thanks

I think somehow my code is printing 2 times. See following example
