Patch for DECTalk Express driver

[Tony Baechler]

I'll have to get back to you on this, but from my recollection of the 
manual, the Express has no volume control except the knob on the unit. 
The DECtalk PC does have a volume setting which is probably the command 
you gave. I tried the command for the DEC PC with my Express and it 
didn't do anything. I would have to look at the manual again to make sure.

Is there a way to send commands directly to the synthesizer with 
Speakup? If I echo them to /dev/ttyS0, speech becomes very sluggish and 
unresponsive. The same thing happens as soon as hal starts. That only 
seems to be a problem with the DEC Express. I have a Doubletalk LT and a 
Trippletalk which don't do that. There used to be a file called "synth" 
which let me do that but now it only contains the name of the 
synthesizer. The synth name used to be in synth_name which disappeared.
