===Model 204 version 7.1===
Version 7.1 is certified for all IBM supported releases up to and including the following:

<li><b>Model 204 v7.4:</b> <br />Currently fixed by zap 74Z4552.  Contact [[Contacting Rocket Software Technical Support|Technical Support]].</li>
<li>IBM z/VM 6.3</li>
<li><b>Model 204 v7.1 (and lower):</b> <br />Workaround: Set z/OS 2.1 TCP DefaultSndBufSize to 16384.</li>
</ul>
</ul>
<p class="note"><b>Note:</b> Model 204 version 7.1 is not supported on IBM z/VSE.</p>
