+config MB_RTU_ENABLED
+	bool "Modbus RTU support"

+config MB_ASCII_TIMEOUT_SEC
+	int "Character timeout"
+	depends on MB_ASCII_ENABLED
+	default 1
+	---help---
+		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.
+
+config MB_ASCII_TIMEOUT_WAIT_BEFORE_SEND_MS
+	int "Timeout to wait before sending"
+	depends on MB_ASCII_ENABLED
+	default 0
+	---help---
+		Timeout to wait in ASCII prior to enabling transmitter
+
+		If defined the function calls vMBPortSerialDelay with the argument
+		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
+	int "Maximum number of Modbus functions"
+	depends on MODBUS
+	default 16
+	---help---
+		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
+	int "Size of Slave ID report buffer"
+	depends on MB_FUNC_OTHER_REP_SLAVEID_ENABLED
+	default 32
+	---help---
+		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 MB_FUNC_OTHER_REP_SLAVEID_ENABLED
+		is set to 1.
+
+config MB_FUNC_OTHER_REP_SLAVEID_ENABLED
+	bool "Report Slave ID function"
+	depends on MODBUS
+	default y
+	---help---
+		If the Report Slave ID function should be enabled.

+	depends on MODBUS

+	---help---
+		If the Read Input Registers function should be enabled.
+
+config MB_FUNC_READ_HOLDING_ENABLED
+	bool "Read Holding Registers function"
+	depends on MODBUS
+	default y
+	---help---

+	bool "Write Coils function"
+	depends on MODBUS
+	default y
+	---help---
+		If the Write Coils function should be enabled.
+
+config MB_FUNC_WRITE_MULTIPLE_COILS_ENABLED
+	bool "Write Multiple Coils function"
+	depends on MODBUS
+	default y
+	---help---
+		If the Write Multiple Coils function should be enabled.
+
+config MB_FUNC_READ_DISCRETE_INPUTS_ENABLED
+	bool "Read Discrete Inputs function"
+	depends on MODBUS
+	default y
+	---help---
+		If the Read Discrete Inputs function should be enabled.
+
+config MB_FUNC_READWRITE_HOLDING_ENABLED
+	bool "Read/Write Multiple Registers function"
+	depends on MODBUS
+	default y
+	---help---
