(STILL BEING REVISED, and beware that not all uarts behave the same)

Table showing whether a particular byte triggers a break condition when
receiver uart is configured at a higher baudrate than the transmitter uart and
both are 8N1.

always = byte always triggers break regardless of preceding data
init   = byte triggers break at least if preceded by line idle state
***    = not sure, dependent on subtle details of uart behaviour
