-savebin
+Just like with the low-level select command, there is no built-in MF/DF
+selection.

+savebin File_ID out-bin-file
+
+This command selects the specified EF (just like with low-level select and
+readef, you need to be in the right MF/DF directory) and saves its complete
+content in a raw binary file on the UNIX host file system.  This command
+supports all 3 types of EF (transparent, linear fixed and cyclic) and uses the
+correct READ BINARY or READ RECORD commands based on the SELECT response.
+Record-based EFs are read in the order of increasing record number and are saved
+in the host binary file with all records simply abutted together.
