Right.  Well, sometimes there are "termination characters" that
denote the end of a message sent from the intrument to the computer
and vice versa, see
<http://pyvisa.sourceforge.net/pyvisa/node17.html>.  They are not
EOI though but \r or \n.

Besides, normally you work on an abstraction level where you don't
worry about the EOI line or any termination characters.  For
example, you work with <http://pyvisa.sourceforge.net>.  ;-)

Tschö,
Torsten.
