I am facing the same problem and tried your solution but no success 
I think i have gone wrong somehere. something thats too obvious and overlooked
I have enabled the ISP_E jumper in LPC2378-SK board
I tried connecting to the board with the following settings:
. 8 bits
· No parity
· One stop bit
· No handshaking or flow control
· 9600 baud
· No local echo
I checked the Serial Cable also by short circuiting Tx and Rx pins its fine
I am using a generic Serial Cable (Do we need some special cable
?)
I couldn't get the echo on sending '?' to the device
Pls help !!!
