One way to handle this is to set BI or MBBI Records on the iocs and display
the text values in your screen.  The problem with this approach is that you
need screen space for every possible text message.

Another way to handle this is to display the output from a GenSub record,
which can have multiple inputs and multiple outputs and code inside to
choose what gets displayed.  This would be one way to implement queuing up
channel access puts.

Given the nature of the messages that you describe below, another option to
consider would be the alarm handler.
