The online source includes javacomm/CommPortOpen.java , which provides a framework for
using Java Communications API; it does pretty much all the work except for actually reading
or writing. You subclass CommPortOpen and write a converse() method to read and write on
the InputStream and OutputStream , which are exposed as the inherited fields is and os ,
respectively.

Table 10-5 lists additional programs in the online source package.
