command:
:ROUTe[n][:CHANnel[m]]:CONFig?
syntax: :ROUTe[n]:[CHANnel[m]]:CONFig?
description: Queries the switch configuration of the instrument. For each channel, the minimum and 
maximum channel number of each port is given.
NOTE
parameters: none
response: <j>,<k>;<l>,<m> as text string where:
<j>  is the first port character on the left
<k>  is the last port character on the left
<l>  is the minmimum port number on the right
<m>  is the maximum port number on the right

command:
:ROUTe[n][:CHANnel[m]]:CONFig:ROUTe?
syntax: :ROUTe[n]:[CHANnel[m]]:CONFig:ROUTe?
description: Queries the allowed switch routes of an instrument.
NOTE
parameters: none
response:  [A.....Z],[1.....n];[A.....Z],[1.....n].[A.....Z],[1.....n]   as a text string. 
"," separates input and output ports of a single connection.
";" separates parallel connections
"." separates possible switch states
example: rout2:conf:rout? → A,1;B,2.A,2;B,1
2x2 x-over switcch:
state 1: When A to 1 then B to 2nd connection (straight)
state 2: When A to 2 then B to 1st connection (cross-over)
