On all platforms except IQS-600 and FTB-500, for

compatibility reasons, you can connect to a
module with a valid instrument command and a
valid LINS (such as
Lins10:SOURce:DATA:TELecom:CLEar).
However, there will be no way for other sessions
to know that you are connected to this
instrument.
If the command is not executed successfully, the

possible reasons could be:
The module is already connected to

a different client session.
The provided information does not

correspond to a valid LINS.
