Each of these messages have a well defined bit orientated structures that can be mapped in to the first few layers of the OSI stack (datalink, network, transport and session).

...or you might be able to write a module for the Wiretap library in Wireshark (see the "wiretap" subdirectory) that can directly read your ASCII files.
