There was a problem hiding this comment. nit: not sure if it is worth but since |
||
| { | ||
| // GetFiles can return unexpected results because of 8.3 matching. | ||
|
|
||
| // Like /dev/tty | ||
| if (name.StartsWith("/dev/tty.")) | ||
| { | ||
| ports.Add(name); | ||
| } | ||
| } | ||

This file is not being referenced in the csproj. Are planning to include support to macOS? If yes the csproj need a few updates besides including this file.

yes. This is part I tested so far so I was not comfortable enable full build.
