<p>When <a class="issue-link js-issue-link" data-error-text="Failed to load issue title" data-id="426978059" data-permission-text="Issue title is private" data-url="https://github.com/RIOT-OS/RIOT/issues/11310" data-hovercard-type="pull_request" data-hovercard-url="/RIOT-OS/RIOT/pull/11310/hovercard" href="https://github.com/RIOT-OS/RIOT/pull/11310">#11310</a> was merged, it was difficult to evaluate that applications using getchar would have problems afterwards.</p>
</blockquote>
<p>Removing that input works by default, should trigger checking what uses input.</p>
<blockquote>
<p>The current state of this PR fixes everything in one go. If you want to move fast, just ACK and merge this one. I can split out the tes application if you want.</p>
<p>An alternative (to move fast) could also to just add stdio_uart_rx to applications requiring it (as done in the 3 first commits), but it will leave the codebase in a non satisfactory state.</p>
</blockquote>
<p>No does not work, I noticed it must only be added if <code>stdio_uart</code> is used.<br>
Adding it would blacklist boards using <code>stdio_rtt</code>…</p>
<blockquote>
<p>When you reported <a class="issue-link js-issue-link" data-error-text="Failed to load issue title" data-id="443856082" data-permission-text="Issue title is private" data-url="https://github.com/RIOT-OS/RIOT/issues/11525" data-hovercard-type="issue" data-hovercard-url="/RIOT-OS/RIOT/issues/11525/hovercard" href="https://github.com/RIOT-OS/RIOT/issues/11525">#11525</a>, it would have been better if you provide the list of impacted applications precisely, since you seem to know it already, I have never seen this list, except here.</p>
</blockquote>
<p>If it was not clear from the original PR what can be impacted and how to solve it. Then the PR was not ready to be merged.</p>
