how to detect HART modem presence and version

Is there a way to detect whether or not there is an actual HART modem connected to a particular port without any reference to an instrument. I shouldn't have to have an instrument plugged in for the modem to respond. A HART modem with no instruments must be different than nothing, so there must be some way of determining this without knowing a valid tag name. I may have more than one HART loop on more than one port and I want to list all valid ports that have a HART modem connected to it. I may have an Agilent or a MODBUS device connected to one of the other ports, so not all ports that are connected to something will be HART ports.
