[BRLTTY] Using a Handy Tech display with BRLTTY on Windows

Fri Apr 22 08:21:54 EDT 2016

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
