Inventor 0.4.0 on Windows 10 with camera running JeVois 1.11.0.
Anything valid I type into the console returns blank lines (or maybe white text on white background...) followed by OK
Invalid commands return an 'ERR Unsupported command'
Text from my own code will only show in console on Inventor if it starts with ERR or INF.
Tried, Terse, Normal, Detail and Fine filters in Console tab and made no difference.
