Status streams are recorded as plain text, as for GCF files.
9.2.4 SUDS file format
Scream! supports recording in the USGS SUDS 1.x format, using the
same rules for file and directory names as for GCF files (see above), but
using the extension .sud.
Files in SUDS format must represent a contiguous period of time. If a
discontinuity is detected in the incoming data stream, then the file
which is currently recording will be closed and a new file opened with
a file-name and time stamp matching the start of the new file. This
operation will take place regardless of the options you have specified
for Granularity, although the Granularity options will still work.
The files generated have STATIONCOMP and DESCRIPTRACE header
structures, using the following fields:
sc_name.network and dt_name.network : The last 3 digits of the
System ID.
sc_name.st_name and dt_name.st_name : The first 4 digits of the
Stream ID.
sc_component : v for Zn streams; n for Nn streams; e for En streams;
m for the Mux channels Mn.
