[FYI] hrpsys system (HiroNX and Nextage) outputs frequent escape characters with Docker

[7675t]

This is not a request for fixing, just a information for hrpsys users.

While using the hironx_ros_bridge package within a interactive terminal of Docker container,

rtmlaunch hironx_ros_bridge hironx_ros_bridge_simulation.launch

it output very frequent escaped characters to the console.

The system itself seems work just fine.

I think this is caused by some RTCs (guess Beeper) writing something to /dev/console, and Docker may not be able to handle them correctly.

A workaround is to change the permission of /dev/console NOT writable for anyone like:

$ chmod a-rw /dev/console

I hope this save someone's time.
