The return values ​​from the controller through the terminal aren't displayed correctly.

Thank you for the report!

Here's a fix for that issue:

The problem in that case is the switching of the logging function in KRCC. To get terminal output just in time K-IDE has to switch logging function on and off. Therefor K-IDE uses two logging files which are exchaned every 500 ms. When switching form one logging file to the other there is the possibility to loose some characters. You'll see that issue if your robot program writes many messages to the terminal via TYPE or PRINT. The same happend when a terminal command is accomplished.

The fix inserts a small wait time (0.5 s) after a command is send.
