Please keep it on list, some other may have the same install issue or someone could have better insights on installing telnetlib.

telnetlib is part of the standard modules in my Debian squeeze(python 2.5). Looking at the doc, it looks like it's available for python 3 as well. Strange that you don't have it.

Did you try

import telnetlib

?

Note that in the code above I forgot the EOF, which is very much dependent of the equipment itself.

You may have to write
t.write('*IDN?\n')
or
t.write('IDN?\n\r')
