Buffered cli commands

[groggy7]

It seems like the cli commands im writing over ptmx are first buffered, then gets executed. Is it possible to not print these at all?

This would have to do with the ioctls of your terminal. The example from the readme provides a show-case on how to set the terminal in raw mode to properly use a shell within a pty.
If you need to manually fine control the line discipline (in this case the ECHO mode), then you can use syscall.Ioctl or a library like golang.org/x/term.
