Details:

Butterfly seems to send '?' often enough to keep serial_drain looping
forever. I therefore just ad-hoc changed timeout.tv_usec from 250000 to 25000
and now it works for me anyway. But why does drain loop in the first place?
Shouldn't the purpose just be to get rid of old waiting input?

Regards,
