This is a developers release. In other words, code may not work as expected, or
may not work at all. See CHANGES and TODO to know what is (not) working in this
release.

There are two code files which are not part of HPTalx code, but I have been
using them for development and debugging. They are specifically written to test
the XModem protocol, without the burden of the rest of the code (GUI is not a
coder's friend). If you want to help with the XModem protocol, you'll probably
find them useful.
