I just tried to find if there is a safe way to output stuff to the host software:
From what i have gathered, ultimaker uses the reprap5d driver on repg. And lines sent starting with "echo:" should be just displayed.
https://github.com/makerbot/ReplicatorG/blob/master/src/replicatorg/drivers/reprap/RepRap5DDriver.java line 702
pronterface has I think a similar feature, but with "DEBUG_" :/
https://github.com/kliment/Printrun/blob/master/printcore.py line 90
however, i am not really sure why there were problems with the eeprom sending, unless some line started with "start".
