kandi X-RAY | rxtx Summary

rxtx is a Java library. rxtx has no bugs, it has no vulnerabilities, it has build file available, it has a Weak Copyleft License and it has high support. You can download it from GitHub, Maven.

Serial Port rxtx library. Version 2.1.8 is: - source code taken from rxtx-2.1-7r2.zip - added Maven POM - digitally signed with recognized certificate - compiled against Java 1.3 (as original rxtx). Currently I’m working on version 2.3.0: - added Findbugs build checks (107 deficiencies reported on Low threshold, 21 on Default, all fixed !!!) - Java 1.7 - some new features…. This is an attemp to revive the old but very good rxtx library that allows for using serial ports in Java. I was using rxtx 2.1.7 for many years. But as my projects have evolved from IDE build through ant to Maven and JDK from 1.1 to 1.8 this was aparent that rxtx is unmaintained. So i tried to get the sources (now not easilly avaiable) of latest stable version (stable in terms of used in many production system) and continue that great piece of software on github. The intention is to release version 2.2.0 with very minimal changes to 2.1.7r2 codebase. Just make it clean Maven project and add digital signature for all classes (because of a need to use it in applets). Version 2.2.1 will undergo some refactoring to meet contemporary Java good practices.

One solution would be to simply handle the exception and stop populating the variables (after giving them some sentinel value up front). This could be done with something like:

How to catch all kinds of interrupt Requests in jSerialCom library?

As we all know, jSerialCom is a high-quality Java library for reading serial data; Previously, RXTX was also a good choice,

So in jSerialCom, how to catch all kinds of interrupt events like RXTX?

In RXTX, there are these java statements to catch various interrupts event

QUESTION

How to get data output to the application via the com terminal?

Asked 2020-Nov-11 at 17:10

Good afternoon, I'm using a sketch for a test that uses an RS-232 connection. I need to understand how and what commands to type in the com-terminal in order to get and see the data in the application window of this sketch near the list of text variables, I have attached a screenshot. I am completely new to this business, tell me the solutions.

This is needed for debugging, sometimes for configuration. I attached a sketch and code, you can check it. The sketch works correctly if the application is installed com0com.exe on the computer and the com port is open via the terminal. The meaning of the code is to send a sequence of bytes to the COM port and display data (numbers) on the screen for variables in applications.

I wonder if there is something wrong with copying std::function as I do in the constructor of the s2lp_custom_ikm class?

No.

The std::function copies in your constructor (both the initialiser and the body) are safe.

The program snippet shown does not contain a bug capable of the symptoms you report.
