There is a bit of a description on the workings of achieving break on the AMIGA
in the RKM Inc+Autodoc manual under serial.device ... 
obviously you are meant to use the serial device to do the break for you..
but there is enough information there (and with the knowledge of custom chips)
to do it at a lower level.

& mind you i'm not advocating it! &
