Most protocols distributed with the x-kernel come with a test protocol in the protocols/test directory. These protocols typically send a number of round trips for messages of various sizes and report the total time for the test. The most common test protocols are configured into the protocol library, but some may have to be copied and compiled directly in a user's build area. Test protocols compiled into the protocol graph start up automatically with the rest of the protocols.
The behavior of test protocols can be modified by various command-line and ROM file options. See the man page for the TEST protocol in Appendix A.
