I just recently discovered that if your ISP tool (by whomever) fails at a higher baud rate it is probably because of three issues: 1. There is an error in the Philips LPC2xxx User Manual.

Hello, I've just come across this on one of our PCBs. This is a proven board and code which a technician has just updated. He was manually manipulating P0.14 via jumper to access ISP, but had not removed power. After this the board will not start up after reset unless JTAG is present. Doing a reset then attaching the debugger shows the code to be stuck in a loop in the bootloa...
