> Does Ethereal capture packets on serial interfaces

If the serial interfaces appear as network interfaces (e.g., interfaces 
that "ifconfig" can report on UN*X systems), then, if the OS supports 
capturing on those network interfaces, Ethereal should be able to 
capture packets on the interface.

If you want to do passive third-party capture - i.e., if the serial 
interface is connecting two other machines - you *might* be able to use 
a card from Endace:

along with their library and a version of libpcap built to include 
support for their cards - you'd have to make sure Ethereal uses that 
library, either by building a special version linked with that version 
of libpcap, or building a shared-library version of libpcap and 
installing it in place of the version on your system, if Ethereal is 
linked with a shared-library version of libpcap.

Several different types of network ports run at gigabit speeds.  If it's 
a gigabit Ethernet port that appears as a network interface on your 
system, Ethereal should be able to capture on it.
