[En-Nut-Discussion] Problem: read uart port

[Nathan Moore]

Read will block if there is no data to be read.  Blocking is NutEventWait on
an event that is triggered by data arriving at the uart.If the baud is
extremely high and data is steadily coming in you could end up eating all
time between the processing of read and rescheduling with this thread
getting run again immediately.  This isn't likely.
Nut doesn't have anything like select or epoll that I know of.
