<h1 align=center>Source-Level Debug with Crossview</h1>

<!--INDEX "Source-level debug with BSO/Tasking's Crossview" xvw3r xfw3r -->
<!--INDEX "abs file" -->

To use the debug <a href="mondef.htm">Monitor</a> with BSO/Tasking's
Crossview, connect the serial port that Crossview will use, to the Monitor's
tty0 (the console) on the target board.  i.e., Crossview only uses one
serial port.<p>

If necessary, use the <a href="c_set.htm">set</a> command to set your
<a href="mondef.htm">Monitor</a>'s prompt to "PMON> ". Crossview is
hardwired to expect that string, and will not work with any other value
(note the space after the ">").<p>

Compile and link modules with the -g option.  This will generate the
.abs file that is required by Crossview. For example,<p>

<pre>
	pmcc -g -o bubble bubble.c
</pre>

Invoke Crossview,<p>

<pre>
% xvw3r bubble.abs -i -E /dev/tty1 -S 9600		Unix
C> xvw3r bubble.abs -i -E com1 -S 9600			MSDOS
-- this includes downloading of bubble.abs
