No you aren't. I've got a blind friend and her 
system (which I'm currently doing some work on) runs 
Windows 98.

Your modem does *not* run at 38,400 bps. If it's a 
V.34 modem, it'll run at a max of 33,600 bps, and 
the odds are that thelocal telecommuncations 
authority (FCC in the US, different agencies in 
other countries) won't authorize it to run above 
31,200 or so.

For best results, you need to set the comm port to 
115,200 bps.

Easiest way in DOS is probably to grab a FOSSIL 
driver such as X00 and use it as a serial driver and 
use the included utility program XU to set the bit 
rate and enable the FIFO buffer.

If you want a copy, I can email it to you. You'll 
need a copy of pkunzip to extrat the files from the 
archive.

That's the same speed as Lin's system. It runs JAWS 
quite well. Alas, JAWS costs $2000. Unless you can 
get your local commision for the blind or the like 
to buy it for you.

It doesn't require dedicated speech cards, it'll 
work with any sound card that Windows supports.
