<p><span class="h-card" translate="no"><a href="https://ioc.exchange/@azonenberg" class="u-url mention">@<span>azonenberg</span></a></span> ok apparently it&#39;s just any 32 bits that are not the CRC of the preceding packet</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> I believe that&#39;s the 10/half CSMA/CD feature to detect if two nodes start talking over each other.</p><p>I&#39;m not familiar with the details of half duplex operation as to date, all of my devices have been full duplex only.</p><p>I will have to add half duplex support to my MAC soon though, because my switch needs to support talking to some Siglent gear using an ancient chipset that only supports 10/half operation</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> I want to know the story behind the last sentence.</p>

<p>this might be one of the _least_ specific (but not completely non-specific) paragraphs in any specification i&#39;ve ever read</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> yeah i may patch mine to do the same. Interesting.</p>

<p><span class="h-card" translate="no"><a href="https://ioc.exchange/@azonenberg" class="u-url mention">@<span>azonenberg</span></a></span> do you have any idea how to implement half duplex mode? I have no clue wtf they mean by &quot;jam signal&quot;</p>

<p><span class="h-card" translate="no"><a href="https://ioc.exchange/@azonenberg" class="u-url mention">@<span>azonenberg</span></a></span> yeah I think that&#39;s technically noncompliant. I&#39;ve designed my MACs to allow for SFD only, it&#39;s easier to do that anyway</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> interesting i think my macs require at least one 0x55 byte. I&#39;ve never seen a phy that violates that in the wild, at least</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@neuronakaya" class="u-url mention">@<span>neuronakaya</span></a></span> Hi, do you have any samples on what kind of artwork you make? I could be interested in commissioning. 🙂</p>
