Yeah, I guess you're probably right there. In that case, perhaps someone can 
guide me. I've seen scads of HP models on ebay. However, often the 
description isn't clear enough to determine if the unit just supports sync, 
or just async, or just X.25, etc. etc. Having a penchant for HP gear (have 
you noticed?hehe), does anyone know what model of HP protocol analyzer is 
the right one for RS232, sync & async? Some of the ones I've seen there 
APPEAR to be very specific for things I wouldn't want and I'm just not up on 
the HP models of this.

Thanks for any tips!
