Overriding default timeout on HPIB.

Question asked by VRFuser on Jun 17, 1999
You can create a new instrument in the manager, which may use the same
driver but with a long timeout for example (ie: Spectrum Analyzer XY long
Now you can use this Instrument whenever you want to make measurements where
you need to have a long timeout.
The only possibility to read the current setting of the timeout I am aware
of, is to read the file and interpret it.

this also implies setting the the default timeout to the value last used in
this particular program.
