I've been working on this on and off for a month or so now. I've got a steep learning curve when it comes to the internal workings of Windows machines, so I doubt that I fully appreciate all of the nuances of what I've discovered. So far...
Ethereal, a free open-source protocol analyzer, claims to support Cisco HDLC. I was in touch with the developers and they informed me that Ethereal could support ISO HDLC only if WinPcap supports it. I was next in touch with the developers of WinPcap, who informed me that WinPcap could support ISO HDLC only if Windows supports it (i.e. if it is part of NDIS). Far as I can tell, it doesn't and it isn't. Elan Digital Systems, Ltd. makes a PCMCIA card that claims to support ISO HDLC and comes with it's own drivers. How to interface those drivers to a protocol analyzer application is beyond my current know-how. The WinPcap folks suggested that if the drivers exported HDLC as "an ethernet adapter" it could possibly be made to work. Elan offered me a 30-day trial period to try to make something happen. I'm leaving on another extended business trip soon, so it'll have to wait I suppose. In the mean time, I thought I'd share what little I've learned thus far in hopes that some brilliant individual(s) might have something a little more insightful to add. Is there a much easier way to go about this with a Unix or Linux box? There are, of course, hardware-based protocol analyzers, such as the Agilent Advisor, that do a great job of decoding serial protocols. We bought a few several years ago. Seem to recall that they were between $10k and $20k, depending on options.
