<p dir="auto">When using <code>gnutls-cli</code>, the client will always send as much data as it was in the biggest line sent thus far (i.e. Enter does not insert a 0x00 character in the buffer). That means the server sees garbage (data from previous lines) when receiving the shorter lines from client.</p>
