Lpc2000

If are you trying to connect directly from LPC UART pins to mobile phone's UART eliminating RS232 transceivers in both end, there need not be any software change. You have to open the phone cover and solder onto PCB. No hardware inverter is required. But do not connect LPC pins directly into phone RS232 jack.
