serial synths and 2.6.36/37

[Kitty Litter]

The only way I got speakup to work with the audapter when I compiled 2.6.34 
several months ago was to remove the error checking in serial.c, I think it 
was, regarding stealing the ports. I have a lot of problems with missing 
letters when key echo is on whether I type fast or slow. I don't have the 
knowledge to fix either of these problems so I guess my choice is to live 
with it or use windows even more than I do already!
