+Tutorial</title><shortdesc>Steps required to implement a port of the Serial Port Driver. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>The actions needed in porting a Serial Port Driver are based on the experience
+of porting the template reference board port. Note however that the code shown
+here is idealized to show the basic principles; it is not an exact copy of
+the template port code. </p>
+<p>In the template reference board port, the <filepath>.mmp</filepath> for
+the physical device driver is <filepath>...\template_variant\datxtemplate.mmp</filepath>.
+This is one of the PRJ_MMPFILES referenced in the Variant's <filepath>bld.inf</filepath> in
+the <filepath>...\template_variant\...</filepath> directory, and means that
+the Serial Port Driver is built as part of the Variant. The source for the
+driver is contained entirely within <filepath>...\template_variant\specific\uart.cpp</filepath>. </p>
