Hi Don: Well, thank you, I read your comments maybe 4hours ago, but wanted to 
have a good breakfast before I make sense. Anyway, I must set the DecTalk in 
RS232 mode instead of U S B. I have `absolutely no idea how I would bipass 
speakup to type directly in to the DecTalk? If I did, then next time these 
settings drop, I could send a sample-and-see what happens? Even an original 
author of Speakup says the settings are wrong, but neither him nor the person 
who maintains Debian Speakup files have any DecTalk units. Seemingly this unit 
is on /dev/stty0
Lets take these 3 Speakup settings 1 at a time. First volume which in this 
driver  go from 60-86, I keep at 86, but when it drops, I think it ends up at 
70 or 71.
Rate. I keep rate at 229. Rate goes from 75-610. Alot of times when it 
initualizes, its at 180.
Pitch. I like it at 111, setting go from 50-349 or so. Maybe pitch drops to 80?
And lastly I have inflection crankedup, with the following command, which I 
think I got from some1 on the DecTalk list many years ago
echo "[:dv pr 250]" >> /sys/accessibility/speakup/synth_direct
All 4 of those drop suddenly while either scrolling with Speakup review on the 
numpad, or any number of other ways. After they drop, I must go to the Speakup 
control-pannel-and-jossle each setting by 1. As soon as it gets moved by 1, it 
comes back nearly where it was. An even stranger thing, my Linux expert looks 
at the settings while its dropped, but they show regular values as I want them. 
O, I also must run that inflection command again, so I keep that in tty9 
history, as I run it alot. I am not a programmer, but if there are specific 
thinks you want me to try, I would be happy to. Thanks in advance.
Chime
