No-wait doesn't wait if there is no data. Async doesn't wait if there is data but less than you ask. Say there are 5 bytes of data on our port test, Then read-io test buffer 8 would block on a sync port, 'no-wait or not. Async would read the 5 bytes, throw an error that it would be blocking (that you catch) and you continue later on. --Maarten
