Hi. First of all, thanks for all the great work being done!

If I open console app with its input redirected in a classic console, when the input ends the console app can act accordingly:

For example:


:: Create command
C:\Users\gerar>Echo Prompt [TEST] $P$g > MyCommand
C:\Users\gerar>Echo cd .. >> MyCommand

:: Execute with redirected input
C:\Users\gerar>cmd < MyCommand

Microsoft Windows [Version 10.0.19043.1165]

C:\Users\gerar>Prompt [TEST] $P$g

[TEST] C:\Users\gerar> cd ..
[TEST] C:\Users>

:: Child CMD detects End of Input and terminates automatically. 
C:\Users\gerar>

I am trying to replicate this using ConPty with no luck. If I create a pseudoconsole, send the input but then try closing the input stream (hInput) to signal end-of-input, with different approaches, but none of them seems to work. The client console app keeps waiting for more input.

How can I signal the console app running in a pseudoconsole that the input has ended?

Thanks!
