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.

Every
time my ubuntu machines download a new kernel, generate a new patched
kernel
package. I never got around to it though. I was using a sed command to
comment out the line that caused serial synths to not work so that
automation was possible. Part of the problem here is that I have kind of
given up on serial synths myself. I have been depending more and more
on the
combination of a braille display and software speech. It seems to me
that
using a hardware speech synth is going against the grain these days.
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:
