sEndEvent (Function)

In french: sFinEvénement

Disables the detection of an event on a serial port. The event was managed by sEvent.

This function returns information regarding the server.

Example

// Détection de caractères sur le port COM1
sEvent(1, sEveCharReceived, "Lecture")
sEvent(1, sEveBreak, "Break")
...
sEndEvent(1, sEveBreak)
...

// --Procédure Lecture(NumPort, Event)
Trace(sRead(1, sInEntryQueue(1)))

Syntax

<Result> = sEndEvent(<Port number> [, <Event to stop>])

<Result>: Boolean

True if the function was run,
False otherwise.

<Port number>: Integer

Serial port number (1, 2, 3, ...32 for COM1, COM2, COM3, ... COM32).
Port number returned by sOpen (if this function was called with a port name).

<Event to stop>: Optional Integer constant (or combination of constants)

Event whose management must be stopped. If this parameter is not specified, all the events managed on the port are disabled.
sEveBreak Receive a "Break line" event
sEveCharReceived Receive a character
sEveCTS Change of CTS status
sEveDSR Change of DSR status
sEveEntryQueue80 The input buffer is full at 80%
This constant is not available.
sEveError Detect an error on the line
This constant is not available.
sEvePrinterError Printer error detected
This constant is not available.
sEveRing Detect the "Ring" signal (ring)
sEveRLSD Change of RLSD status
This constant is not available.
sEveTransmitCompleted The output buffer is empty

Remarks

Closing the port

When closing the port, all the events managed on this port are disabled. When re-opening the port, sEvent must be re-run to define the events managed on this port.

Using an external library: RXTX

In Java, the use of serial and parallel port manipulation functions (functions sOpen, sWrite, sRead, ...) requires the presence of an external library: RXTX.

This library includes a Jar archive and one or more native libraries that depend on the operating system on which the application is run. To use these functions:

the Jar archive (RXTXComm.jar) must:
- be found in the same directory as the Java application generated by WINDEV,
- be found in the execution classpath of the application,
- be directly included in the generated application (from the wizard for Java generation).
the native libraries corresponding to the operating system on which the application is run must be found:
- in the same directory as the Java application generated by WINDEV,
- in the path of the application libraries (librarypath).

You can download the RXTX library and its documentation from the following link: http://users.frii.com/jarvi/rxtx/index.html (link valid at the time of writing).

Attention: Infrared port management not available in Java.
