I have answered Hugo already, but I forgot to include the mailing list.

For the actual master branch at github use
   result = char(usbtmc_read(fd,readbytes))
to get the text string.

Meanwhile I ported usbtmc to be included to OF instrument control within
the port2forge branch. The syntax will change a little bit, but you
still have to use char(usbtmc_read(obj,readbytes)) to get the result as
a string.

BR,

 I finally got the first answer string coming back from my Keithley. Thank you very much Stefan for all your patience and the
help offered
