Ctrl+O not working with SSM start-session

[jbbarth]

When using ipython (an improved shell in the python ecosystem), "Ctrl+O" is the canonical way to add a new line in a given cell, so you can add multiple instructions before executing.

It turns out Ctrl+O doesn't work within a aws ssm start-session session:

• expected behaviour: a new line is added to the cell
• observed behaviour: nothing happens

Version: 1.2.497.0 (latest stable), installed via Homebrew

Steps to reproduce:

• aws ssm start-session --target <an instance with linux>
• sudo pip3 install ipython
• /usr/local/bin/ipython
• Ctrl+O (should add a new line)

I'm more than happy to help in the resolution, do you have any pointer where I should start to look at? I saw #29 but it seems to be more about signal handling.

I saw #29 but it seems to be more about signal handling.

The title of that issue might be misleading. I think it's the same general issue: handling of control codes, possibly related to termios.

Closing this one in favour of #29, I didn't read til the end, it looks like it's the same issue indeed. Thanks @justinmk3!
