Doesn't seem so :-(
I am logging .last_string() after EVERY command in my script
and usually there is no output. So far the only command I've tried
that actually causes last_string() to work is cs-status.
For examples, cs-get-position-samples leaves an empty last_string.

Hmm, ecacontrol seems to be pretty broken here, scripts that
run with pyeca.ECA_CONTROL_INTERFACE() will disconnect
from the engine with ecacontrol.ECA_CONTROL_INTERFACE().
Darn.
