Hi team.</div>

I am Vasundhara, a software developer at Microsoft working on Narrator team. We use the BrailleTTY Open source code in Narrator to interact with Braille devices. Currently, we are trying to migrate our build process to Onebranch (Azure DevOps build system for
Windows components). For that, we have to build the BrailleTTY code using msys1 (as that is what it currently supports). </div>
