Java enabled phones supporting serial port access

Does anybody know a Java enabled mobile phone beside the Motorola iden family that supports access to the serial port ? As far as I can see there are no such phones on the market.

Low Level Serial Port Access

This question has gone unanswered several times on this forum in the past but I thought I would try it once more.
Is there any Java API that is in, or will work with J2ME to allow direct read and write to the serial port similar to the functionality that javax.comm provides for j2se.
This would be useful for a project where a palmos device is used to communicate with equipment used to monitor industrial processes.

Some MIDP 1.0 devices support access to the Serial
Port.
I have done it with Motorola i85, i50 (iDen) and
Motorola T720i.
I think 95cl also supports it. I'm ALSO having problems with serial port access on
my T-Mobile Moto T720i phone. I've had MUCH success
with the Nextel i85, i50, i95cl, etc phones, but the
same code isn't running on the T720i.
What do I need to do differently???
Thanks,

Serial port access time slows in version 6 to 7 upgrade

Hi - I am in the process of upgrading an project from LV 6 to LV
7, the serial port access works well in LV6 but after the
upgrade, the serial port access is slow in LV if the application is
compiled into an exe. We are running Windows 2K on all machines
and have installed the LV7.0 runtime engine on the PC that is running
the executable. If I run the application on a machine that has
the full LV7.0 development software on it, the executable runs
just like it used to under LV6.0
What am I forgetting?? The application is built into one exe that
has all of the sub vi's included. I have checked the box on the
application builder that says included serial port support.
Help! - We have 3000 PCBs sitting in manufacturing waiting to go to test until I solve this problem
Thank you

Hi
I just recently finished a project in which I had to upgrade code from LV 6 to LV 7.1. After I did that the serial port actually worked but all the Fieldpoint devices that were connected to the system didn't work. The problem ultimately was the NI Fieldpoint Drivers. After I installed the newest drivers from NI everything worked perfectly. I don't know why your problem is occurring, but I wanted to reasure you that there isn't a problem with the serial ports when upgrading to LV7.1 (I don't know about LV7).BTW, I had LV6.1 development system installed on the computer, but didn't have the LV7.1 (All I had was an EXE file).
So, try installing the newest drivers. Maybe that can help.

Java enabled phones?

This is probably a very rudimentary question, but how many phones today are java-enabled (in the sense it can run midlets)? 20%? 50%? 90%? Is there a list of manufacturers and models somewhere?

I think only 5-10% of the phones today are Java enabled - only applies to GSM Networks. Motorola's iDen has bragging rights about deploying Java enabled phones since they introduced the i50sx. Japanese network also has been using Java enabled phones.
Anyway, the top GSM phone manufacturers, Nokia, Siemens, Sony-Ericsson, Motorola, will be releasing Java enabled phones soon. Nokia 7210, 7650, Siemens SL45i, M50, Sony-Ericsson's P800 are all Java enabled.

Infrared / Serial ports access in MIDP for Palm

Hello,
Do you guys know if MIDP for Palm allows to connect to the IR / Serial ports ? If yes, any examples ?
Thanks,
Vadim.

I'm very interested by your discussion, i have searched a lot of information about midp and the access to the serial port.
The specifications of midp says that the comm protocol is not available in midp.
The IBM J9 Java VM is supposed to be full midp implementation but only only for x86 processors. The lcdui package is not available with the J9 VM for palm. The lasts contact i have with ibm about this subject, they said that they will implement lcdui but they can't say when .... perhaps in 2002.
I don't know any other Java VM witch have a full midp implementation ... Kada VM will be but i don't know when ...
If you have any other information, i'm very interested
Thanks by advance

After Effects scripting: Serial port access?

Hi,
Does any one know if it's possible to access the computer's serial port using an After Effectsc script?
I'm building a motion control script and I'm wondering if I can use a script to read the values of a keyframed parameter(e.g. a slider effect on a solid layer) to send serial port commands to move my rig.
Regards,
Ihab Ali

I don't think that ExtendScript for AE ships with a way to do that out of the box, but in the Javascript Tools Guide for CS5, there is a section titled "Integrated External Libraries" which reads:
You can extend the JavaScript DOM for an application by writing a C or C++ shared library, compiling it for the platform you are using, and loading it into JavaScript as an ExternalObject object. A shared library is implemented by a DLL in Windows, a bundle or framework in Mac OS, or a SharedObject in UNIX.
You can access the library functions directly through the ExternalObject instance, or you can define an interface that allows your C/C++ code to create and access JavaScript classes and objects.
All Adobe Creative Suite 4 applications support this feature.
So you can probably write an app in C or C++ which communicates directly to the machine's port, and then call functions you declare in that code via ExtendScript. Sorry I couldn't be of much help here, but that's where I would start.

Need faster serial port access

I am using javacomm for serial port communication and the performance is too
slow for my needs. I am comming with an embedded app from an NT machine
with my java app. For benchmark purposes I hava VB app that can also talk
to this embedded app. The round trip communication time for the VB app is
20-30 milliseconds but the java app takes ~200 milliseconds. I think I could
improve performance by writing to the serial port directly instead of going
through the javacomm api which I think is slowing me down. Is it possible to
to a low-level file open and write directly to the serial port? And if so, how?
Thanks,
Michael

MichaelSlowing down of communication process depends upon code content as well. if u can put ur code here, may be u can get some feedback concerned with speed.
you can not directly talk at a serial level but make a component in say C n can use native methods to access that component. But that component would be very much comparable to Win32com.dll.There would be speed difference but that difference would not be enough to warrant 'too much'

Which java Enabled phone u use for testing application in real condition?

Hi Every one.
As it is a list which some people do Mobile developing i have come to
ask a question about Java Enabled Mobile phones.
My question is : Which Java phone u use to test your application ? (out
of simulators in real world)
do you use Simulators until project end , or you deploy on mobile phones
some times ?
Thank you

OK, I've used a workaround...

Serial Port Access

Hey,
How do I read data from the COM3 port on my computer. I have the javax.comm thing all setup but need to figure out how the data comes in from a device plugged into that port. Having the data display on the fly as they are being read should be explained please. Thanks a lot.

Hey,
Have a look at this example:
http://java.sun.com/products/javacomm/javadocs/SimpleRead.java
You need to adjust some things though.
Hope this helps.

Access serial port through AIR

isnt there any extensions or API buit for accessing serial
port from AIR.
i am designing a vending machile applicaton in which a coin
drop is detected and corresponding images or message is displayed.
MDM Zinc 3.0 allows serial port access but worths more than
what it deserves. does AIR has some similar functionality.
Any help.

I'm not too hot on this subject, but would it not be possible
to use Binary Sockets to connect to another app on the machine that
could connect to a serial port?

import javax.microedition.lcdui.*;
import javax.microedition.io.*;
import javax.microedition.midlet.*;
import java.io.*;
public class TestSerial extends MIDlet implements CommandListener
Form form1;
TextField tf1;

Command command1;
StreamConnection sc;
OutputConnection oc;
Connection connection1;
/****************************DefiningConstructor*****************************/
public TestSerial()
disp1=Display.getDisplay(this);
command1=new Command("Start",Command.OK,1);
form1=new Form("Serial Port Connection");
form1.addCommand(command1);
form1.setCommandListener(this);
public void startApp()
disp1.setCurrent(form1);
public void pauseApp()
public void destroyApp(boolean b)
public void commandAction(Command c,Displayable d)
if(c==command1)
try
/************Establishing serial port connection****************/
connection1= Connector.open("comm:0;baudrate=9600");
connection1.close();
catch(Exception e)
System.out.println(e.toString());
}Please mail your precious suggestions regarding this problem as soon as possible.
Thanking You,
Taqi Raza.

I am not sure about sun wireless toolkit 1.0,
check the settings, -> permissions... (We have this in sun wireless toolkit 2.3, where i can set the security options)
