With d.mon the things written to the Command Console tab in main GUI
(g.gui) are written to the stdout, i.e. they should be visible in your
command line. This was not possible in 6.4 with wxGUI but it is possible
with version 7.

You can actually use commands in the Command Console tab (including the d.*
command) but it is not the same as the standard command line (it has pros
and cons).
