inline breakpoint

Thanks for the answer and I will use this if there is no other way but is there any way of achieving this programatically?

Have a look at the instruction set of the '51 and try to find an instruction that acts as a break point. (Hint: There isn't one).

In VC++ I think you can do something like __asm int3 to force the program to break out to a debugger.

And what makes you think that a '51 will act anything like a PC ?

The monitor 51 has to somehow break out to the debugger, looking at the debug options it uses the serial interrupt. What does it do to the serial port to cause the breakpoint so I can simulate this in my ASSERT?

Many Thanks,
Martin.

Breakpoints are set in Mon51 by replacing the instruction where you set the breakpoint with an LJMP into the monitor.
