Frank, I need your help here. I need to write an application that send
to 15 devices a lot of OIDs to poll. I'm trying to send one V1 PDU to
each device with all the OIDs defined by the user. It works OK, but I
have a problem when the user put a wrong OID in the list. 

For example,
OID1= 1.3.6.1.2.1.25.2.3.1.5.1
OID2= 1.3.6.1.2.1.25.2.3.1.5.2
OID3= 1.3.6.1.2.1.25.2.3.1.5.5

But OID3 does not exist in the device.
In this example, when this happens the device return "null" for every
OID and NOT just for the wrong one.

I tryed to use GETNEXT but this command didn't return the OID that I try
to query, it return (like the name) the next element.

Can you point me any ideas?

Beste regards, Eduardo.-
