Hello, I was just trying to get BRLTTY working on Windows. However, it seems unable to communicate with my Handy Tech Modular Evolution 88 display.
The display is connected via USB and I'm using the driver provided by Handy Tech. The display works fine with NVDA. I set up BRLTTY to use the serial over USB port, COM7 in this case. A debug log has been attached. Does anyone have an idea what is happening here? Bram
