Originally created by @amoldeshpande on GitHub (Jul 4, 2019).

Environment

Windows build number: 18362.207
Windows Terminal version (if applicable):

Any other software? VS2019 with Windows 10 SDK 17763

Steps to reproduce

Launch the sample

Expected behavior

it should work

Actual behavior

The call to SetConsoleMode fails with ERROR_INVALID_PARAMETER. If I ignore this error, the sample works as written. No idea if it would still work with an actual VT100 client.

ETA: The ReadFile in PipeListener thread never returns while the child process is happily printing to the console window it was spawned with.

So, I don't really understand how this thing illustrates anything about ConPTY.
