I just posted a simple Win32 cmd line tool to calculate the optimum register 
settings for a LPC214x UART peripheral.
I am not aware if all the LPC2k UART peripherals are the same or not.  If so 
great.  I was working against the LPC2148 user manual.

It seems the equation in the user manual to calculate the baud rate is 
incorrect.

It should be:
Baudrate = 
(PCLK/(16*(256*PRE_SCALE_MSB+PRE_SCALE_LSB)))*(MulVl/(MulVal+DivAddVal))

opposed to:
Baudrate = 
(PCLK/(16*(16*PRE_SCALE_MSB+PRE_SCALE_LSB)))*(MulVl/(MulVal+DivAddVal))

I replicated the user manual example baud table using my software with 
modified equation.

Minor typo in the user manual:  The percent error value for the optimized 
56000 baud is incorrect, it should read 0.1600 opposed to 0.0160.

I hope you find it useful.
