How to verify HPIB communication?

I have hooked up (for the first time, novice here!) a HP3457a DMM to a 82350 PCI GPIB/HPIB card (running in an old PC with win98) and have loaded Agilent IO Librabry 14.0.
-The HP3457a is only recognized as a device at address 22, but no equipment ID.
-The card is recognized, and I can send commands such as DISP 2, tester to the DMM ( manually via Interactive IO) and see that they work.
-Problem: When I try to do any read (via Interactive IO; send and read or read button) I get back an error message; VI_error_TM0: A timeout occurred and VISA error code 0XBFFF0015 (-1073807339). When sending some commands it does appear that the numerals of the voltage that was currently displayed are being returned.
- I am thinking that I have something configured wrong for listening. The 3457 seems to have substantially different commands than current instruments.
I would like to verify that the hpib is talking and listening properly before I install more equipment, how can I verify that the DMM is actually sending out data and it is being received?


Note: I am stuck with using the 3457 because I have to create a BDAT file using HPBASIC (or maybe another way?), and the commands seem to be specific to only a few model DMMs. I am running win 98 because I think it will get along better if I end up using the DOS version of basics. I am waiting for a reply from the HTBASIC folks.

I started out with a NI card, but then found out (in docs) that some of the commands I need require an HP card. I got partially installed on the NI card and seemed to have a similar problem.
