Use this command to display breakpoint information about any or all-active breakpoints in the system.

While the system suspends a process at a breakpoint, this instruction causes the display of the suspended process ID and the register values when it encounters the breakpoint. These values differ from those printed with the query process command, as the latter prints the values at the time of the last process swap.
