Problem with Telnet Agent

[joedson]

I'm trying get data from the MikroTik v4.10,
but all data, independent of the command,
come with the same value "0"; for instance,
if I try the command "put (10+20)" in the
"Executed script" of the Telnet Agent,
its returns "0" instead "30".

Does somebody know how to fix it?

PS: Any command works fine when
I try get data from Ubuntu 11.04

Thanks in advance!
