console-conf doesn't work well if using screen on Mac

[Liming Wang]

On Mac if using screen to connect serial, console-conf can't display well, with overlapping texts and flickering screen. We have tried following ways, but none of them works.

1. change options of screen
2. make the terminal window full screen
3. change the terminal max columns to larger, such as, from 80 to 200.
4. try on arm boards and x86 machine,

And we followed the instructions[1] to install minicom, and use minicom to connect serial, and console-conf works well.

So the problem that console-conf doesn't work well under screen on Mac.

Can you tell us what the environment variable TERM is from screen on Mac?

Please include the name of the terminal emulator and the version of
OSX/macOS used

@chipaca @zyga

1. Using the default terminal program in macOS:

$ export|grep TERM
declare -x TERM="xterm-256color"
$ screen /dev/tty.usbserial-AI03RVDT 115200
# open a another windows in screen
$ export|grep TERM
declare -x TERM="screen-256color"

2. OSX/macOS version: OS X EI Captitan(version 10.11.3)

Just curious, does tmux work better?

Thanks

@seth-arnold

Does tmux support serial? I search in google and don't find it does.

[Seth Arnold (seth-arnold)]

Sorry, I missed that screen was doing serial work for you. Thanks.

[John Lenton (chipaca)]

That should work, as it is in the terminfo we ship in core. Just in case, can you try with different, less capable TERMs? Start with vt100 for example (see /lib/terminfo for the ones available -- it's not the full set)

I'm moving this to the subiquity project. Please report a snapd task if you feel there is something that should be improved in snapd itself.
