Actually a Lazarus question, not an FPC question.

Currently on Linux, all terminal IO is redirected to
Menu: view > debug windows > console

But, that is a very simple text console without terminal functionality. 
You will see text, and be able to enter text... nothing else.


On Windows the OS opens a new terminal window for the debugged app. On 
Linux the caller (here IDE) would need to start a terminal (xterm, 
gnome-term, ...) and run the app inside => that is not supported currently.

There are a few "workarounds"

1) Tools >Options > debugger backend : there is a setting about PTY
If you have a terminal open, and know its pty, then you can enter this 
pty in the settings, and all in/output is redirected.

2) (not tested myself)
Run the app in gdbserver inside a terminal, and use the gdb server 
debugger to connect to it.
