<p>Hi Dave,</p>
<p><br>
</p>
<p>I send the actual logs and test results.</p>
<p>First test, 300 ms start delaying time, device: /dev/ttyACM0,
yesterday tryed serial patch is applied too:<br>
BRLTTY started infollowing time:<br>

/dev/ttyACM0 device is measured in 15:20, 15:24 and 15:25 times.<br>

End time when measure ended: 16:06:04<br>

<p>Precise, the entire used modified command with usual works when
the delaying time is 300 MS or higher:<br>
LANG=C brltty -ldebug,usb,serial,inpkts,outpkts -b fs -d
ttyACM0+baud=57600 -L brltty_usb_serial_16:05_300ms.log &&
python3 serial_measure.py<br>
<br>
Other measurements is not need, because baud rate this situation
setted correctly.<br>
Braille display is detected correct with following time:
<a class="moz-txt-link-abbreviated" href="mailto:2024-12-30@16:05:04.035">2024-12-30@16:05:04.035</a><br>
</p>
<p>Very interesting, when I restarting entire system, braille
display is not initializing.</p>
<p>When I trying this working command variation, some time BRLTTY
correct set the baud rate and initializing the display, some time
not.</p>
<p>I tried increasing delaying time with 500 Ms (you will be seeing
the modified waittime related patch), some time initializing the
display, some time not.</p>
<p>In the /etc/brltty.conf file not possible set this baud rate
related modification for example with Braille parameters the FS
driver?</p>
<p>So, partially we founded a working solution, begin going the good
direction.</p>
<p>I think the 1000 or 2000 MS perhaps will be too long wait time.
What do you think?</p>
<p>If you thinking need more increasing the wait time with larger
value from 500 Ms, I will be repeat the test.</p>
<p>So, BRLTTY is more time right starting this USB adapter when I
using the -d ttyACM0+baud=57600 option.</p>
<p>Normal -d ttyACM0, or -d /dev/ttyACM0 newer automatically
changing the baud rate in adapter side this usb serial adapter my
experiences.</p>
<p><br>
</p>
<p>Hopefully you helps this diagnostic logs.</p>

<p>Hi Dave!<br>
<br>
So I completely understand what you want to test.<br>
To be honest, since we tested a new patch, I automatically
removed the ready time delay code line fix that you suggested on
December 24th, but I can easily restore it.<br>
So I will repeat the test with the two patches.<br>
I will report back with the results and log files by this
afternoon at the latest.<br>
Thanks your patience and every help,</p>
<p><br>

<pre class="moz-quote-pre" wrap="">I meant "ready delay", i.e. the added line in braille.c:
descriptor.serial.options.readyDelay = 200;
Please test with both the serial patch and this line added to the braille driver.
