Update of bug #56757 (project octave):

                  Status:                    None => Need Info              


Follow-up Comment #4:

Ah, I just did a little searching and found that the following sequence

\x1b[6 q

is intended to change the shape of the cursor to an IBeam shape in certain
terminal emulators. So maybe something in the PS1 setting or some other
configuration is trying to use this escape sequence, which is rejected by the
Octave terminal emulator.

Does this look familiar to you at all in your settings?

As far as I can tell there is nothing in Octave that would be doing anything
close to this, so at worst this is Octave not supporting a particular terminal
escape sequence that it may never support, and complaining loudly about it.
