The idea was that you call seqChanShow with the thread id for the
program that does not get the event you think it should get. The above
table is printed when the thread id argument is absent (or not the
thread id of a running program instance); it is there to help you to
chose a correct thread id (second column).

The sequencer's shell commands (of which seqChanShow is one) are
documented at http://www-
csr.bessy.de/control/SoftDist/sequencer/Reference.html#shell-commands
