You can use HyperTerminal (which comes with Windows) to communicate with it, but it's quite likely you would need to know the protocols involved - which are likely to be specific to the meter - not just the serial protocols (speed and number of bits), but the communication protocol the meter uses.
 
I was at one point interested in a radio shack meter that had RS232... until I found out the serial protocol...

what it did was send a long series of packets, where all the data bits LITERALLY represented the status of each of the LCD segments on the display (7 segments per digit, plus all decimal points, signs, and other various bits) and I believe it only operated at 9600 baud. Talk about a crude way to send data! :lol:
 
In Ontario, RadioShack recently changed their name to "The Source (circuit city)".
