 #
+# CONFIG_MODBUS - General ModBus support
+# CONFIG_MB_ASCII_ENABLED - Modbus ASCII support
+# CONFIG_MB_RTU_ENABLED - Modbus RTU support
+# CONFIG_MB_TCP_ENABLED - Modbus TCP support
+# CONFIG_MB_ASCII_TIMEOUT_SEC - Character timeout value for Modbus ASCII. The
+#   character timeout value is not fixed for Modbus ASCII and is therefore
+#   a configuration option. It should be set to the maximum expected delay
+#   time of the network. Default 1
+# CONFIG_MB_ASCII_TIMEOUT_WAIT_BEFORE_SEND_MS - Timeout to wait in ASCII prior
+#   to enabling transmitter.  If defined the function calls
+#   vMBPortSerialDelay with the argument CONFIG_MB_ASCII_TIMEOUT_WAIT_BEFORE_SEND_MS
+#   to allow for a delay before the serial transmitter is enabled. This is
+#   required because some targets are so fast that there is no time between
+#   receiving and transmitting the frame. If the master is to slow with
+#   enabling its receiver then he will not receive the response correctly.
+# CONFIG_MB_FUNC_HANDLERS_MAX - Maximum number of Modbus functions codes the
+#   protocol stack should support. The maximum number of supported Modbus
+#   functions must be greater than the sum of all enabled functions in this
+#   file and custom function handlers. If set to small adding more functions
+#   will fail.
+# CONFIG_MB_FUNC_OTHER_REP_SLAVEID_BUF - Number of bytes which should be
+#   allocated for the Report Slave ID command. This number limits the
+#   maximum size of the additional segment in the report slave id function.
+#   See eMBSetSlaveID() for more information on how to set this value. It
+#   is only used if CONFIG_MB_FUNC_OTHER_REP_SLAVEID_ENABLED is set to 1.
+# CONFIG_MB_FUNC_OTHER_REP_SLAVEID_ENABLED - If the Report Slave ID
+#   function should be enabled.
+# CONFIG_MB_FUNC_READ_INPUT_ENABLED - If the Read Input Registers function
+#   should be enabled.
+# CONFIG_MB_FUNC_READ_HOLDING_ENABLED - If the Read Holding Registers
+#   function should be enabled.
+# CONFIG_MB_FUNC_WRITE_HOLDING_ENABLED - If the Write Single Register
+#   function should be enabled.
+# CONFIG_MB_FUNC_WRITE_MULTIPLE_HOLDING_ENABLED - If the Write Multiple
+#   registers function should be enabled.
+# CONFIG_MB_FUNC_READ_COILS_ENABLED - If the Read Coils function should
+#   be enabled.
+# CONFIG_MB_FUNC_WRITE_COIL_ENABLED - If the Write Coils function should
+#   be enabled.
+# CONFIG_MB_FUNC_WRITE_MULTIPLE_COILS_ENABLED - If the Write Multiple Coils
+#   function should be enabled.
+# CONFIG_MB_FUNC_READ_DISCRETE_INPUTS_ENABLED - If the Read Discrete Inputs
+#   function should be enabled.
+# CONFIG_MB_FUNC_READWRITE_HOLDING_ENABLED - If the Read/Write Multiple
+#   Registers function should be enabled.
