On DOS the default mode of operation is through the parallel port which is a much faster link. Even BRLTTY is much snappier with a parallel port connection. But unfortunately the parallel port protocol information isn't available and only an old binary-only library exists which just can't be linked with BRLTTY using recent versions of gcc. But to reduce the sluggishness a lot you can change the default serial baudrate from 9600 to, say, 38400. On BRLTTY's side you need to edit Drivers/Alva/brlconf.h accordingly and recompile. On the Alva side you need to change the baudrate using the built-in menus accessible by pressing PROG+HOME+CURSOR simultaneously. Nicolas
