Braille Blazer problems

[Garrett Klein]

Hello all,
I am running Slackware 9.1 with Speakup 1.5 using my Braille Blazer as a 
synthesizer. I, however, am having multiple issues with it. For one 
thing, when too much text gets sent over the serial port, it turns 
itself off and back on, which destroys my punctuation/pitch settings (I 
can fix the pitch and speed, though). My second problem is 
Speakup-related. I've seen it in Speakup 1.0, 1.5, and CVS speakup 
(which, might I add, made my blazer sound quite weird). This problem is 
that it does not announce uppercase letters in a higher pitch than 
lowercase ones. This has also happened when using my Braille Lite 40 as 
a synth. I've tried a warm reset, and that didn't help. Sometimes it'll 
say some letters higher when spelling a word, but I think it doesn't 
just do the uppercase ones in that case, it's hard to tell. Case 
sensativity works in JAWS for DOS, BTW.
I'm looking into getting a DoubleTalk LT, so I won't have to worry about 
these problems anymore. Either that, or possibly getting a TrippleTalk 
USB and using its serial port, would that work with speakup? Any 
suggestions to fix these annoying issues would be appreciated.
Thanks in advance,
Garrett
