Jason Morley<p>Over the past few days, I&#39;ve made a number of improvements to the Psion Software Index, an auto-generated catalogue of software for Psion palmtops and notebooks. Performance of the full index listing is much improved with added support for filtering, and program pages are cleaner with download links for all files.</p><p><a href="https://software.psion.info/" target="_blank" rel="nofollow noopener" translate="no"><span class="invisible">https://</span><span class="">software.psion.info/</span><span class="invisible"></span></a></p><p><a href="https://mastodon.me.uk/tags/psion" class="mention hashtag" rel="tag">#<span>psion</span></a> <a href="https://mastodon.me.uk/tags/retro" class="mention hashtag" rel="tag">#<span>retro</span></a></p>

The Last Psion | Alex<p><strong><a href="https://oldbytes.space/tags/plptools" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>plptools</span></a> update!</strong></p><p><strong>Ports</strong></p><p>The <a href="https://oldbytes.space/tags/HaikuOS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>HaikuOS</span></a> port works with on-board serial ports. However, USB RS232 adapters do not work. This is because of an issue with the <code>usb_serial</code> driver in Haiku. DTR and RTS can't be set reliably, and RTS and CTS can't be detected.</p><p>There is still one small issue with the Haiku port. A GNU regex test in <code>./configure</code> is segfaulting. This can be bypassed, but we want it fixed. That involves delving into autotools, so we'll see how I get on!</p><p>Both the <a href="https://oldbytes.space/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>FreeBSD</span></a> and <a href="https://oldbytes.space/tags/NetBSD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NetBSD</span></a> ports are working! With a combination of brute force and the help of a few FediFolk, these now compile. (I did think that the NetBSD port was severely broken, but I was just using the wrong serial device. Sigh.)</p><p>MacOS is still stable and happy.</p><p>We're not planning on adding any more ports unless people really beg!</p><p><strong>Bugs</strong></p><p>Just a handful of small fixes, like <code>plpftp</code> not segfaulting any more when you press CTRL-C. I might have introduced a new bug into plpftp regarding Daylight Savings... I'll try to fix that soon. In my defence, Psion's implementation of DST is, to put it politely, rudimentary.</p><p><a href="https://oldbytes.space/tags/Psion" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Psion</span></a> <a href="https://oldbytes.space/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>retrocomputing</span></a> <a href="https://oldbytes.space/tags/retrodev" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>retrodev</span></a></p>

The Last Psion | Alex<p><strong><a href="https://oldbytes.space/tags/plptools" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>plptools</span></a> update!</strong></p><p><strong>Haiku</strong></p><p>The <a href="https://oldbytes.space/tags/HaikuOS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>HaikuOS</span></a> port is now <em>mostly</em> working, with caveats. Everything compiles except <code>plpfuse</code>, which might require migrating <code>plpfuse</code> to FUSE3. I've been able to send and receive files using <code>plpftp</code>, but RS232 DSR checking has to be disabled in the code. I don't want to speak too soon as it could very well be my mistake, but there might be a bug in Haiku's implementation of <code>ioctl()</code> for serial ports. Stay tuned...</p><p><strong>FreeBSD</strong></p><p>The <a href="https://oldbytes.space/tags/FreeBSD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>FreeBSD</span></a> port currently has issues with linking to readline, but I'm sure that's fixable. However, a different issue has come up involving FreeBSD's implementation of the <code>timezone</code> global variable. This, in turn, might have uncovered some very old, slightly iffy code when working out timezone offsets.</p><p><strong>Other platforms</strong></p><p>The <a href="https://oldbytes.space/tags/macOS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>macOS</span></a> port is running fine at the moment, thanks to <span class="h-card" translate="no"><a href="https://mstdn.fr/@captfab" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>captfab</span></a></span> and <span class="h-card" translate="no"><a href="https://mastodon.me.uk/@jbmorley" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>jbmorley</span></a></span>'s sterling work. If you're on macOS, check out Reconnect.</p><p>I'd like to resurrect the <a href="https://oldbytes.space/tags/NetBSD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>NetBSD</span></a> port for a few reasons, not least because you can still run the current release of NetBSD on a Series 5. I have no experience with NetBSD, so that's my challenge for this afternoon.</p><p>There are indications that plptools has at some point worked on <a href="https://oldbytes.space/tags/HPUX" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>HPUX</span></a>, <a href="https://oldbytes.space/tags/IRIX" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IRIX</span></a> and <a href="https://oldbytes.space/tags/AIX" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AIX</span></a>. I personally feel that these ports probably don't need to be resurrected.</p><p>The code also mentions <a href="https://oldbytes.space/tags/Solaris" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Solaris</span></a> - I'd certainly consider working on an <a href="https://oldbytes.space/tags/IllumOS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IllumOS</span></a> port, if people were interested.</p><p>Interestingly, there's no mention of <a href="https://oldbytes.space/tags/OpenBSD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OpenBSD</span></a>, but again I would consider working on that if people are interested.</p><p>This is very much a *NIX/POSIX suite of tools. A Windows port isn't going to happen any time soon, unless someone wants to try building it using cygwin. I'm not saying it will never happen, but it's not a priority.</p><p><strong>Misc</strong></p><p>A couple of small bugs have been squashed by Reuben, including an issue where logging didn't go to <code>stdout</code> when using the <code>--autoexit</code> switch.</p><p><a href="https://oldbytes.space/tags/psion" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>psion</span></a> <a href="https://oldbytes.space/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>retrocomputing</span></a> <a href="https://oldbytes.space/tags/retrodev" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>retrodev</span></a></p>
