+shterm
+^^^^^^
+
+  The USB7032EVB1 supports CMON in PROM.  CMON requires special
+  serial interactions in order to upload and download program files.
+  Therefore, a standard terminal emulation program (such as minicom)
+  cannot be used.
+
+  The shterm subdirectory contains a small terminal emulation
+  program that supports these special interactions for file transfers.
