Subject: Osborne 1 Break

Although I have not checked it out, I assume that the overlays for the
MEX (and perhaps a few other ) modem program(s) for the O1 have the
assembly code for implementing a "break" using the uart chip in the O1.

These overlays can be found in the simtel20 archives:  micro:<cpm.mex>.
