+    ----------------------------------------------------
+    To send a file to the target, first make sure that the serial port on the
+    host is configured to work with the board:
+
+      $ sudo stty -F /dev/ttyS0 57600

+
+    Start rz on the on the target:
+
+      nsh> rz -d /dev/ttyS1
+
+    Then use the sz command on Linux to send the file to the target:
+
+      $ sudo sz <filename> t </dev/ttyS0 >/dev/ttyS0
+
+    Where <filename> is the file that you want to send.
+
+    The resulting file will be found where you have configured the Zmodem
+    "sandbox" via CONFIG_SYSTEM_ZMODEM_MOUNTPOINT.
+
+    You can add the az -v option multiple times, each increases the level
+    of debug output.  If you want to capture the Linux rz output, then
+    re-direct stderr to a log file by adding 2>az.log to the end of the
+    rz command.

+    If you don't have the az command on your Linux box, the package to
+    install rzsz (or possibily lrzsz).
