[AG-TECH] Gentner AP-Ware?

Hi - quick followup - looks like it was a combination of things. Definitely a baud rate issue, but it also took 2 reboots to the Gentner. (?)  Perhaps something to do with the firmware upgrade didn't take first time around? I don't know. Things seem to be working great now though. 

Never could get the software to run on Win98, and on Win2k it eats a whole processor, but I can live with it.

Thanks for everyone's responses.

Are you using a standard straight-thru DB9-DB9 serial cable? I wonder if 
it's a flow control thing or some hw mismatch that is triggered by the new 
software. Also doublecheck the baud rate matches between the gentner (on 
the front panel) and apware.

The meter lights flashing make me wonder if your gentner has been somehow 
set to be in slave mode. Aha. From the ap400 docs:
