Hart communication with a terminal program

Hi,
i am trying to communicate with a Rosemount 3051C differential pressure sensor by using a hart modem which is plugged in a RS232 interface (COM1).
For sending and receiving commands and data i am using the following terminal program. (http://www.viddata.com/include/RS232HD50.exe)
Meanwhile, i am able to change the slaves address by sending a hex code. But when i send Hart Command 1 in order to read from the slave, i never get any answer from the slave. Does anybody know what could be the problem?
Thanks!
Mike
