Description |

AFailCount |
Number of attempts to make in reading the line of text. |
string - Line of text read from the IOHandler.
ReadLnWait is a string function used read a line of text from the IOHandler. ReadLnWait attempts to read a non-blank string value using ReadLn.
If data is not available or a timeout occurs, ReadLnWait will retry the operation until the number of attempts in AFailCount have been exceeded. The default value is MaxInt, and essentially indicates that ReadLnWait should wait until a non-blank line is read from the IOHandler.
Set the value in ReadTimeout to indicate the number of milliseconds to wait for each read before a timeout occurs ans the attempt fails.
Use ReadLnTimedout to determine if the read failed due to a timeout condition.
