Communication API for Linux

I want to develop an application in Java for Linux that uses serial port .
But java.sun.com provides communications API for Windows, Solaris but not Linux ! ! !
Where can I find free java api to drive a serial port easily ???
Thanks a lot

I think you can do this using the version for Solaris/SPARC along with RXTX for Linux (do a search on google), also I think IBM did a JavaCOMM api for linux.

About Java Communication API for Windows

hi
I'm studying Serial Communication in university.
I'd like to know the reason why we can't downlaod Java Communication API for Windows.
I confirmed Comm for Linux and Soralis, but I can't find Comm for Win.
Please tell me the reason if someone know.

For no particular reason Sun stopped supporting the windows version
of that package. I use rxtx which happens to allow for much faster
communication too.
The interface is identical to Sun's version, just the package differs: "gnu.io".
kind regards,
Jos

The package was installed accordingly to "Java(tm) Communications API Linux Installation Instructions":
$ls /usr/lib/libLinuxSerialParallel.so
/usr/lib/libLinuxSerialParallel.so
$env|grep CLASS

Java communication api for windows 64 bit

Hi,
I need communication api for windows 64 bit. Are these api's in developement?
Thanks,
Andrea Todeschini

If you use version 2.0 of the rxtx library then it provides a complete implementation of the javax.comm package.
Version 2.1 does not (its in the gnu.io namespace)

Communications-API: Windows download missing

Hi,
I wanted to download the Communications API for accessing the serial port for Windows but the appropriate download seems to be got lost.
At http://www.sun.com/download/products.xml?id=43208d3d there are downloads for Linux and Solaris only ... so does anybody know what happened with the Windows-version?
Oxy
PS: Sorry for double posting but the other category was really wrong for this topic...

Thank you for the unfriendly answer.
Btw: when do you have tried to search for that
problem last time? You get hundreds of results that
are related to the Comm-API somehow...http://onesearch.sun.com/search/onesearch/index.jsp?qt=javacomm+windows&subCat=siteforumid%3Ajava31&site=dev&dftab=siteforumid%3Ajava31&chooseCat=javaall&col=developer-forums

Adobe needs to develop an api for communicating with HTML Overlays & Indesign Objects

I'm a front-end developer who has been assigned the task of developing one of our client's DPS every month. While I praise Adobe for saving a dying a industry and giving non-developers simple GUI controls, they need to develop an api for communicating from HTML Overlays to Indesign MSOs and other objects.
I've had to do some intense animations/pages; which I in turn simply developed all in HTML5 and did an overlay. The time put into those pages could have been greatly reduced if their was a proper API in place to trigger different MSO and events. Is anybody at Adobe working on this? As DPS matures, and more developers are tasked with making folios it's imperative we have a proper way way to develop.

We had a page for embedded movies in a lightbox; the client said customers were complaining that the folios were too large and took too long to download. So we switched to youtube streaming page, but they wanted a poster and autoplay enabled. If you have ever programmed with mobile video, you'll know devices are extremely difficult to manipulate.
I had to do an html overlay with a bunch of transparent divs for hotspots and buttons. If I could have told Indesign to move different objects layer orders or go to a different MSO it would have saved me hours.
Doesn't DPS support localstorage? Couldn't you guys whip up a little api to trigger events via localstorage?
Off topic, another request:
- enable the safari webkit inspector for debugging connected ipads with folios that have html overlays; you guys don't fully support HTML5 or certain js events and it's extremely annoying and difficult to debug.

64-bit Linux driver/associated SPE API for the Omnikey CardMan 3821 card reader

I am in the process of converting from a 32 bit to a 64 bit Linux machine. In the past I was able to use the SPE API for 32 bit Linux along with the 32 bit Linux ifdokccid device driver. However, using the speapi_lnx-amd64-1.0.1 along with ifdokccid_lnx_x64-3.7.0 isn't working for me. For example, when I attempt to do an SCardCCIDVerifyPIN function call, I get back a 6B80 APDU response. I noticed that the ifdokccid for 64 bit Linux requires PCSC lite 1.5.5, but the SPE API requires PCSC lite 1.2.9-beta7, which I'm guessing is not compatible. I am wondering if anybody has any ideas about how I should proceed to get my OMNIKEY 3821 reader to work in a 64-bit Linux environment?

Alleluia!!!
I think I will write a new rule for myself to follow :
Thou shalt never use ndiswrapper again.
Thanks a lot, wonder, and thanks to you too, Xyne.
FYI, I tried to use something else than ndiswrapper before, but it didn't yield satisfying results. Anyway, thanks.

Need API for Java communicating with RS232

Dear All,
I am a newbie to Java. I have a sensor connected to a microcontroller, and this microcontroller is also connected to a PC through the RS232 (COM 1). I have installed the Java Communications API "Javax.comm" on my PC and was able to run the "BlackBox" sample program. What I require is a simple Java program that will read and show the bytes comming through the COM1 port. If anyone has done anything similar or has an idea of how to go about it, could they please send me some example code, I would be very grateful. Or if anyone knows about any website with such similar examples i would be very grateful.
Thank you very much.
FREDERIC
