Re: Help with serial synths in 4.X kernels

May i ask how one finds contingency plans for your ears, your brain, and your processing? smiles. I am not following this debate closely, but it certainly supports my worries about Linux as a main computing solution. If someone is going to remove the door to functionality, or decide for me how I personally accommodate my body differences, then they are no different than say Microsoft.
Access is a human right in some places,  not a feature.
defining that access begins and ends with the individual, which is why the best access uses a foundation allowing for many ways in so to speak.

Going back to the corner now,

Well, first of all, I didn't mean to say you shouldn't use a serial hardware synth. However,IMO, you would be wise to consider contingency plans. If your livelihood depends on that serial synth, you'd be wise to begin examining your alternatives.

Also, I can't promise to debug the kernel code. When I said check the syslog, I meant for you to check the syslog. If I can find the time to take a look at it, I certainly will but I can't promise that. I suspect that what's happening is that when speakup tries to "steal" the serial port, the return value is no longer just null. When I last traced back the functions that speakup was calling to steal the serial port, it was bullstuff. Speakup called a function that did nothing -- which isn't the fault of the speakup developers. I suspect that those functions now do something -- probably not what we want but something.

It has probably been a year since I last posted a rant on this list about the linux kernel developers. As I write this, I find myself getting all worked up about it again. The one good thing about Trump running for President is that now I have someone I find more arrogant and irritating than the linux kernel development team.

 As Karen and others have pointed out, we all have our own personal speech
 preferences. In my case, I have multiple reasons for wanting serial speech
 to work. I find it easier to hear and understand for one thing. There are
 some bugs in the DECtalk Express module which might be easily fixed, but
 the last unpatched kernel I know of that actually worked was 2.6.32 which
 is no longer supported. Anyway, as requested, here is the dmesg output. I
 don't see anything helpful. I did the following:

 service espeakup stop
 rmmod speakup_soft
 modprobe speakup_dectlk
 rmmod speakup_dectlk
 rmmod speakup
 modprobe speakup_soft
