1.1 About RMHost
RMHost is the host component of RealMonitor. It allows you to perform nonstop
debugging on a RealMonitor-enabled application in a real-time environment. That is,
when using RMHost, you can perform certain debugging operations on a foreground
application while the processor continues to run (and service interrupts) in the
background.
The functionality of RMHost is contained in the RMHost controller,
RealMonitor.dll
,
which provides a standard Remote Debug Interface (RDI) to the debugger. The
debugger communicates with the debug target using the RMHost controller, and
communication between RMHost and RMTarget is governed by the RealMonitor
protocol. These component parts of RealMonitor, and the connection between them, are
shown in Figure 1-1.
