I'm trying to use the RS-232 feature on an Extech multimeter. 

Specifically, I'm looking for the RS-232 setup (baud rate, data bits,
parity, etc), and command set for the RS-232 interface to an Extech
model 380289 multimeter. I've had no success searching for the
device's operating manual. (It's a discontinued model so the manual
isn't available at the Extech site.)

I've also tried all of the usual combinations talking to it with
HyperTerminal but I still get no response from it.

So far, I've gotten no reply to an email that I sent to their tech
support department.

Can anyone give me a clue as to how to talk to this little beastie?


Regards, Bob
