I experience this problem quite frequently on my 2114 board (1.63 
bootloader), especially at 115k baud speeds. Using a 14.7456 Mhz I 
expected updating to be at least hassle free at high bauds (2114 
user manual). However, the process tends to halt & fail somewhere in 
the middle. Normally I'd resort to retrying the update until it 
eventually completes. I'm having the success with 56k baud & below 
speeds and below, with less halts occuring at 56k. Keep me posted if 
u've found the cause of this problem.
