Has anybody captured traffic from a synchronous adapter card in linux ?
I am interested in captured low level framing like hdlc, sync-ppp,
frame-relay, sdlc, lapd, lapb.

>From an ISND adapter, can I capture LAPD,and any B-channel traffic in
linux? Or is like the normal ppp0 capture where I can see only the IP
packets and up.

I have a Blackbox PCMCIA Syncronous RS232 card (IC117A) and I want to
connect a linux box to a Cisco to capture some data on this serial card.

Unfortunately, I have no linux driver for this card, and this is the
only syncrhonous card I have.
But if I know that there is a some chance to capture data from this sync
card that I have, I will try to make it work under Linux.

I know that there is a Cyclades PC300 sync card that has support in
linux kernel but I don't have such a card and it cost around $400, that
is too expensive for me.


Maybe somebody has any nonclasified captured data from a syncronous line
(hdlc, ppp, frame-relay, sdlc, lapb, lapd), and could share that data...

Thanks in advance for any capture of synchronous serial data.
