Installing SUSE with Braille and/or speech

Hi.  If I'm asking obvious questions, I apologise.  When trying to install SUSE
9.0 Professional using my Alva 340 terminal, I'm having a lot of trouble
navigating the text-based YAST utility.  My display isn't tracking properly
throughout the install, as I try to move from button to button, check box to
check box, etc, using the Tab and Shift+Tab keys.  Consequently, I can't really
install it because I can't tell where I am.  Is there a work-around?  Or, is
there a way I could install using speech?  I have a hardware synthesizer,
Apollo II.
