%X In a Transputer environment, where the data exchange and the
synchronizations between any two processes are carried out
by means of I/O operations, the monitoring of the channels
used for implementing the message exchange is of particular
interest. In this paper a method is illustrated for
monitoring the internal channels of an Occam program. This
method introduces little CPU overhead, no additional
communication cost, and preserves the synchronization
behaviour of the two communicating processes. Its
characteristics have been attained by means of a particular
monitoring mechanism, based upon a rather unusual use of
some Transputer machine language instructions, canonically
used to implement guarded communications within the Occam
ALT construct.
