5.3 Upgrading Dynamic C
Dynamic C patches that focus on bug fixes are available from time to time. Check the Web
site http://www.digi.com/support for the latest patches, workarounds, and bug fixes.
The default installation of a patch or bug fix is to install the file in a directory (folder) dif-
ferent from that of the original Dynamic C installation. Digi recommends using a different
directory so that you can verify the operation of the patch without overwriting the existing
Dynamic C installation. If you have made any changes to the BIOS or to libraries, or if
you have programs in the old directory (folder), make these same changes to the BIOS or
libraries in the new directory containing the patch. Do not simply copy over an entire file
since you may overwrite a bug fix. Once you are sure the new patch works entirely to your
satisfaction, you may retire the existing installation, but keep it available to handle legacy
applications.
5.3.1 Upgrades
Dynamic C installations are designed for use with the board they are included with, and
are included at no charge as part of our low-cost kits. Dynamic C is a complete software
development system, but does not include all the Dynamic C features. Digi also offers
add-on Dynamic C modules containing the popular C/OS-II real-time operating system,
as well as PPP, Advanced Encryption Standard (AES), and other select libraries. In addi-
tion to the Web-based technical support included at no extra charge, a one-year telephone-
based technical support module is also available for purchase.
