Read from a module. This is a multifunction read that can read from a module previously opened. Any SeaIO devices attached to that module can then be read from in one of the following ways.

Parameters:

`[in]`	*SeaMaxPointer	Pointer to an open seaMaxModule.
`[in]`	slaveId	Address of the device you wish to read.
`[in]`	type	The read type to preform.
`[in]`	starting_address	Where to start the read; MODBUS is base 1.
`[in]`	range	How many consecutive addresses to read.
`[out]`	*data	Pointer to data storage buffer.

Returns:: int Error code.

Return values:

	>0	Number of bytes of data in the buffer.
	-EBADF	No module open or write error.
	-EINVAL	Null buffer or too much data in buffer.
	-ENOMEM	Low memory.
	-ENODEV	Didn't receive response.
	-EFAULT	MODBUS exception. First byte of buffer contains exception.
