UART help(LPC1114)

Ugh.

Are you really trying to send, as data, a string that contains "WriteRegisterOpt(8, 1, 0x03249249, 0);" and then expect the MCU to execute it?

You can't do that.

(The experienced engineers could, but that is complicated)

You need to write code that reads the data being sent, then upon reception, parse the data to extract the information from it.

You should send data like "0x55, 0x08, 0x01, 0x03249249, 0x00" where the 0x55 represents the function "WriteRegisterOpt()" function.

Assuming that you have a receive buffer you have access to, is could look similar to this:

Receive_Buffer[ 0 ] = 0x55; // This is just an example
Receive_Buffer[ 1 ] = 0x08; //  of the data you wanted to send
Receive_Buffer[ 2 ] = 0x01; //  but in array form
Receive_Buffer[ 3 ] = 0x03;
Receive_Buffer[ 4 ] = 0x24;
Receive_Buffer[ 5 ] = 0x92;
Receive_Buffer[ 6 ] = 0x49;
Receive_Buffer[ 7 ] = 0x00;

Then you should have the ability to group the data:

#define COMMAND_WRITEREGISTEROPT   0x55 // Arbitrary value

Command   = Receive_Buffer[ 0 ];   // the arbitrary value that represents 'WriteRegisterOpt'
Argument1 = Receive_Buffer[ 1 ];   // the 0x08 value
Argument2 = Receive_Buffer[ 2 ];   // the 0x01 value
Argument3 = Get_Value( &(Receive_Buffer[ 3 ]) );// where the Get_Value( ) function converts
                                                // the bytes to that '0x03249249' number
Argument4 = Receive_Buffer[ 7 ];   // the 0x00 value

Then you can write code that runs your send command:

    if( Command == COMMAND_WRITEREGISTEROPT )
    {
       WriteRegisterOpt( Argument1, Argument2, Argument3, Argument4 );
    }

This is not actual code to implement. This should just give you an idea on what tasks are involved in getting your target code to execute routines (within your code) with parameters
