I connect to a server via ssh. Then start a command with a lot of output. After some pages the output is interrupted (not the connection), it stops, and also ignoring key presses. But when the command finishes, I can press a key, and return to the remote shell, and behaviour is normal again (but the rest of the command output is lost). I suspect some undisplayable char in the output? The selected encoding is utf-8 (in konsole).
