Set Adtran terminal width to at least 132

Hi, sorry if this has been solved previously.

I get the following error whenever I try to connect to an ADTRAN device since upgrading to 4.0 and 4.1:

Traceback (most recent call last):

    raise ReadTimeout(msg)
netmiko.exceptions.ReadTimeout:
Pattern not detected: 'terminal\\ width\\ 132' in output.

Things you might try to fix this:
1. Explicitly set your pattern using the expect_string argument.
2. Increase the read_timeout to a larger value.

You can also look at the Netmiko session_log or debug log for more information.

Is there something with the update that I can do differently to stop this?

My code is:

Once again sorry if this has been answered and I’m just being blind

@ktbyers Max terminal width is 132
