Yes, MSComm provides the means to communicate to a hardware device via COM ports, but you must have the Protocol the device.  The protocol determines the commands and how they have to be issued to the device.  Have you contacted the manufacturer of the device?  Are they willing to provide you with the protocol?  If so.. you're good to go.. if not, you may have to reverse engineer the communication..
Here are a few software vendors that provide protocol analyzer software.
