But when a timer AST is triggered, you still need code to check if the
actioal IO completed, if not, then $CANCEL it with some flag indicating
it timed out (so the code that executes when the IO completion AST is
triggered knows the IO was timed out but still process whatever was in
the buffer.

Hoff,s suggestion of the "poll" unix routine may be more appropriate
than trying to apply VMS approach to the unix sockets.


And you still need code that assembles a buffer from possibly multiple
unix IO reads. (aka: on transaction may be delivered in multiple packets)
