[BRLTTY] BRLTTY 4 under DOS

[Christian]

Hi all,
Yesterday I downloaded the BRLTTY 4 for DOS version, but I am having problems.
I edited the config file, located in etc\brltty.conf and specified my display and that it was connected to COM1. But nothing happens when I start brltty.
I then did it the other way by specifying it on the command line like:
brltty -bts but still no luck.
Any thoughts?
Many thanks,
Christian
