I mean see if the device is generating interrupts when it should
receive charactors. ie put a break point at v850_serial_ISR and
v850_serial_DSR and see if they get called. If they are called, narrow
it down a bit and see if you are getting Rx Interupts by placing the
breakpoint in the INT_Rx case of the switch statement in
v850_serial_DSR.
