Remote monitor unable to use control characters #3832

chippey · 2021-02-03T19:23:24Z

When trying to use the remote monitor / miniterm, I'm unable to do things like hit Ctl + T to bring up the menu, or toggle various lines with Ctl + R or Ctl + D

Configuration

Operating system: Linux (Pop!_OS 20.04 LTS

PlatformIO Version (platformio --version): PlatformIO Core, version 5.1.0

Description of problem

Steps to Reproduce

Install pio via Python on remote host and local
Initiate pio monitor with : pio remote device monitor
Hit Ctl + T, or any other Ctl combo other than Ctl + C

Actual Results

You might use the baud rate (speed) 115200 as suggest in https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-321/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fsoftware_features_jetson_nano.html%23wwpID0E0DB0HA

pio remote device monitor --baud 115200

Moreover I have a similar problem with the combo Raspberrypi3B+ and STM Nucleo-64 (USB to Serial):

~$ pio remote device monitor  --baud 115200 --echo

In my case: Ctrl + T followed by Ctrl + H works to get help. Ctrl + T followed by Ctl + I to get information. Ctrl + T followed by b to change the baud rate on the fly. Input of commands or other option result in the error shown above, which seems to be the same as @chippey gets.

When Nucleo64-board is connected directly to my laptop (PopOS 20.10) with pio device monitor --baud 115200 --echo everything works as expected. Echo is used so I see the commands I typing on the serial console:

@chippey A workarround would be to run ssh -t username@host pio device monitor -b 115200 in case you got ssh access to nvidia-nano, where -t stand for Terminal.
If you configure a SSH Reverse tunnel you would even be able to access the nvidia-nano outside of a router without NAT:
In that case the command would be: ssh -t -p <port> <pi@lsserver.uber.space> pio device monitor -b 115200, where port the reverse ssh port.

Thanks for the report! Please re-test with pio upgrade --dev.
