1) Install gnu screen.
2) To find the device run: ls /dev/ttyACM*
3) Run screen e.g. screen /dev/ttyACM0
4) To quit: Ctrl-A then type ":quit"
5) Using \n for a new line with printf doesn't automatically give a carriage return. So use \r\n instead.

try sudo /screen/tty*
Hello,
We are using the LPC1769/CD (https://www.nxp.com/support/developer-resources/evaluation-and-development-boards/lpcxpresso-boards/lpcxpresso-board-for-lpc1769-with-cmsis-dap-probe:OM13085). This shows up as an MBED device on our Ubuntu 18.04 LTS.
We are trying to access the device over Serial comm port
As shown here we are able to access the Serial comm port on ACM0. We also gave the necessary permissions for the OS to access the device.
However, when we use the screen command we don't get any output. See screenshot below:
We also tried using the screen command as suggested by Alex
and we got a response as show in the screenshot.
The device is working on an Apple MAC as shown below:
Please advice how we can get the device to communicate with the Linux Ubuntu.
Thanks
Firmware Team.
