Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Updating libc6 version from 2.24-11+deb9u1 to 2.24-11+deb9u3, the
device file became nonresponsive.
* What exactly did you do (or not do) that was effective (or
ineffective)?
+ libc6(2.24-11+deb9u1) install and cu command (AT Input , OK response)
: This is the result I'm expecting.

* What was the outcome of this action?
As mentioned above, no response was made when updating was done.
However, not all devices are affected. Only some devices are affected.

* What outcome did you expect instead?
As with the 2.24-11+deb9u1 version, I expect that OK will be returned
after entering the AT command to the device file.
