Problem with text in snmp

[cristhiano]

I create one item to get sysdescr.0 of Cisco routers.
And one trigger to verify change of text using diff (myrouter:diff(0)>0).

But trigger is always TRUE.

The problem in text of SNMP have "line feed".
I believe the last or prev have too "carrier return" and so expression not match.

Someone had the same problem ?

Item type is character. If put text not work.

The value of lastvalue have \r and in MySQL dont have \r.
