+<h2>RTEMS appDevGuide Documentation</h2>

+<p>In the Application Developer's Guide the example for the RTEMS TFTP
+filesystem chdir command isn't quite right. The note says that all pathnames
+passed to chdir must end in a / character, but the example doesn't show this.
+The example should be changed as shown below.</p>
+<hr />
+
+<p>The RTEMS TFTP remote filesystem driver now supports a limited form of the
+chdir() system call. One restriction is that all pathnames passed to chdir()
+must end in a / character, so IOC shell commands to change directories must
+be given as</p>

+<p><code>cd ../db/</code></p>

+<h2>epicsReadLine</h2>
+
+<p>src/libCom/osi/os/default/epicsReadline.c used a char variable to hold the
+return value from getc(), and compared this against EOF. getc() returns int
+not char because ANSI C allows char to be unsigned if the architecture finds
+that easier, thus EOF can never be stored in a char on a PowerPC CPU. char
+should be changed to int or signed char.</p>
