J2ME Serial Connection

Hi Guys,
I am trying to write a program that connects to the serial port of my PDA
I use this code:
StreamConnection connection = (StreamConnection) Connector.open("comm:7;baudrate=1200");
but it throws a connectionnotfound exception.
For you information I am running the application on a i-mate PDA (which supports MIDP 2.0) and trying to read from a GPS device connected to its SDIO port. (The SDIO driver maps the port to a virtual (COM 7) serial port)
Any Help please?
Thanks

PC Suite - no USB and Serial Connection Type avail...

I have been trying to solve this problem for days now. I have Windows XP and Nokia 5310. After I installed Nokia PC Suite, there is no USB or Serial connection type in the Connection Manager; it only has Blue Tooth and Infrared conection available. I have install and uninstalled PC suite and used PC Suite Cleaner to clean the installation. I also went into the add and remove program in the control panel and click on "change" to fix the Nokia Connection Manager and Nokia Connectivity Cable Driver. It still didn't work. The thing is that the first time when installed PC Suite on my laptop, it did have USB connection option. Later after uninstalled PC Suite and reinstalled it, it start to have this problem. I am extremly frustrated. Can anyone help please?

Thanks for your reply. I have solved the problem by following your instruction below:
Go to Start --> Settings --> Control Panel --> Software, there you need to uninstall all Nokia software (Nokia PC Suite, Nokia Cable driver, PC Connectivity Solution ...)
Download and run Nokia PC Suite Cleaner
Reboot your computer
Download and install PC Suite here.
Connect your phone via USB cable (if possible use a different USB jack) and follow the instructions on the screen.
Maybe when I uninstalled Chinese version of PC suite, the order in which it was uninstalled was not the one you suggested above. So，I followed your instruction and uninstall order to uninstall PC Suite again. I also uninstalled all the antivirus, spyware, and firewall before I reinstall the PC Suite. It worked; then, I reinstalled all the other security software again after I had reinstalled the PC Suite. Although it worked, I still didn't know what exactly cause the problem the first place, PC Suite version, Security protection software, or the order which it was uninstalled? All it matters is it's working.

Using usb as serial connecting to cisco router not working

Tried using ZOC and securecrt and both shows only /dev/tty-Bluetooth.....
any ideas how can I use USB as serial connection to router?

Hi and welcome to the forums!
GREAT FIRST POST!! Very clear and specific. You don't know how rare that is
Is the laptop in a docking bay?
Content "encryption" meaning Content protection is turned off, right?
Are you able to backup and sync with the Desktop software?
Do you have the correct folders on the card?
Blackberry, music, ringtones, pictures, videos, voice notes?
(blackberry has to be first).
Last one, how did you format the card?
Thanks

Proper serial connections for Sun Fire v250

I recently purchased a (gently) used Sun Fire v250 for use as a workstation. The machine had a graphics card installed by a previous owner, but I accidentally reset the factory defaults on the SCC (I was having a boot problem, and apparently a brain problem).
My question is, how do I connect over serial to make the default boot up options 'screen' instead of 'ttya'? I know from the oracle docs that I need a specific type of serial cable, but I'm unsure where exactly I can go about finding this. Also, once I get the cable what software (for *NIX or windows) can I use to reset the SCC?
Thanks,

Dychron, Inc.Search for a cisco console cable .... this is a typically a 9 pin to RJ 45 ... usually less than say $10 on at least well known auction site.
If you laptop/desktop does not have a serial get a usb to serial converter as well.
If you have a linux desk OS then it is possible to connect to a serial connection ... from solaris you would use tip .... from linux typically use 'cu' (built it) ... if I remember correctly.
Or use recent versions of PuTTY from windows. ... which can also be configured for serial.

Windows 8 using Putty with a serial connection

I am trying to connect to the network console ports using the serial functionality in Putty. I have configured Putty to use the COM1 port when using the serial connection. But each time I try using this serial connection, I receive an error saying "unable
to open connection to COM1...Unable to open serial port."
It worked just fine when using Putty and the serial port over the COM1 in Windows 7, but I no longer have that functionality in Windows 8. Is there a setting that needs to be changed or is Windows 8 not capable of using this feature now?

how do I find out which program is using the port and how do I disconnect it?
I don't know but I just found something that might help using WMIC.
portconnector
Data presented corresponds to this
https://msdn.microsoft.com/en-us/library/aa394358%28v=vs.85%29.aspx
Unfortunately it appears that the Status field is not being used correctly. Also, I don't know how accurate this will be because it is showing me I have a PS2Mouse on my Surface!   ; }
Hmm... more usefully I think in the sidebar I noticed Win32_SerialPort which led me to
Path CIM_SerialController
(e.g. in WMIC) which is showing me more believable information about some COM ports that are being implemented using Bluetooth.
Thanks for making me find this!   ; )
So, for example, presumably you may be able to get some information about your COM2 by entering
wmic.exe Path CIM_SerialController where (DeviceID="COM2") Get /Format:list
Here's one where I don't even need a where clause.  (I did a Get-WMIObject -List *serial* to find this.)
wmic.exe Path Win32_POTSModemToSerialPort Get /format:list
As for getting a Reset done it appears that this may not be implemented by WMI.

Cellphones, bluetooth and serial connections

I have used a GPRS-connection with my Powerbook connected to my cellphone via bluetooth for a couple of years now. However, I have one problem with this setup - I have several cellphones (A, B, C) and subscriptions (1, 2, 3) and I can only connect with the most recently paired phone. In other words, if I first pair A with my computer and try to connect using 1 it works fine. I then pair B and try to connect through 1 (I have moved the SIM-card for 1 from A to B) it still works fine but when I now try to connect using A, the connection, and this is no surprise, fails. The reason it is no surprise is because the computer still tries to connect using B.
I don't know why this happens, but there seems to be some limitation in Mac OS X/the Bluetooth setup process which only allows it to use the most recently paired phone.
In other words, in the situation described above, the only way to be able to connect using A again is to "unpair" both A and B and the "re-pair" A.
Very annoying. However, after digging around a bit in the Bluetooth prefs I found: Devices tab -> select a phone in the device list -> Edit Serial Ports… where you can add serial ports (two different types of serial ports: "Dial-up networking" as well as "Serial port") for your devices and then make them visible in the Network pref pane. I guess this means that it is possible to add a serial port that belongs to a specific BT-device and then create a network location that uses this port/device and suddenly my problem would have disappeared.
The problem is that this window is unsupported. Yes, I have called Apple Assistance and they specifically says that this window is not supported by them, not even if I paid a technician or engineer at Apple (I support more than 20 users at my company that needs this functionality, hence my eagerness to pay for support). They actually laughed at me when I said I was prepared to pay to have this issue escalated.
Back to my question: I have tried to add both types of ports in different combinations but when I try to connect it still fails. In Mac OS X I get the following error message:
The modem has unexpectedly hungup. Please verify your settings and try again.
and a verbose internet connection log looks like this:

Any ideas how to get this to work?

I wonder if just using Network>Configure>Show>Network Port Configurations, then selecting the existing Bluetooth/Serial connection and duplicating it as many times as needed, the editing them wouldn't help... then you could just have a location for eack Phone.

Bad serial connection?

We have a 3510 array here that we are configuring via the serial port at the back of the system.
The 3510 was a dual raid base and it worked fine. Now it is going to be used as a single raid with a JBOD card. The issue is when we fire it up and have a look through the serial connection instead of getting the nice little option screen to configure it we get a screen of unreadable digits and letters.
Does anyone know why this is happening? Could it be a firmware difference between the Raid board and the JBOD board?
ANy help would be appreciated
Cheers

It sounds like a mis-match in baud rate. Try adjusting the speed setting of your terminal window.

Can't HotSync Centro ("Serial connection failed to initialize")

Every time I start my laptop (Sony VAIO, running Vista) I get the following error message: "Serial connection failed to initialize (The selected port, COM4, is not available at this time. HotSync Manager will open the port when it becomes available.)." I haven't been able to HotSync my Centro for some time now, as the port apparently never does "become available".... Any suggestions? Thanks in advance!

How are you connecting to the computer?
What do you have the HotSync Manager set for? A serial connection? ("Local")?
It should be set to "Local USB".

NAC 3310- cannot connect to with serial connection

I have (2) 3310 NAC appliances that someone else set up and configured. I need to access via a serial connection to my laptop to upgrade the software. I cannot connect via Hyperterm. I have 4 other NAC appliances that I can connect to fine via direct laptop serial connection. My hyperterm settings are correct. Log files do not show anything that could be causing this (per TAC). I can access via ssh over the network, and through the web gui.

Short description is, I serial connected to the CAS's to do
a software upgrade, and could not get a connection to either of them. Through troubleshooting it seemed there were other issues going on with the Active CAS. Once I rebuilt (re-installed software) and reconfigured the HA pair, I was able to serial connect to both and then proceed with the upgrade.

Reading/Writing character commands to serial connection

Hey! I'm currently working on a project where part of it is to write a labview program to read and write commands through a serial connection to our PIC24F16KA304 board.
I basically have no knowledge on labview, I've been messing around on it for a few weeks trying to get myself familiar with it but I'm not having much luck.
Essentially I'm programming a train simulation control box. The PIC board will have a sensor that is connected to a train track that sends the character 'A' (for arrived) when a train stops at the station to lab view. I then want to be able to tell Labview to turn a LED on relevant to the station and then respond with the character 'M' for move. I need to repeat this situation for 6 stations
I also need to be able to 'R' for reversing the simulation, 'J' for jump (miss a station) and 'E' for end
If anyone with a bit more experience and knowledge then me can help I would be eternally grateful!

A state machine would be a good starting point for this project (and your understanding of LabVIEW).
You can always wire constants to VI inputs on the block diagram instead of having controls on the front panel that you have to type into. Just right click on the VI >> create >> constant.
The LabVIEW basics will help you out with all of these simple problems.
Good luck,

My thoughts exactly. Adding to what Chrissy posted...
Your question reads like "How do I unlock the door to my car and win the Daytona 500?" The first part is simple (use the constants like Chrissy said) but the second part is much more invloved.
plese take the advise posted above and go thorugh the tutorials and learn to use state machines. AS yo udo this other questions will come up and you should feel free to start a new thread on ech question. Stick with it, play nice and we'll get you to the finish line.

My motor receives data via a serial connection, but it won't move. What am I doing wrong?

Hello everyone,
as the title says, I am trying to use a motor called "MP285" by Sutter Instruments via LabView. The control unit of this motor only has a RS232-output, but I use a Serial-to-Usb-Adapter to connect the device to the PC.
My problem is the following:
I tried to perform a basic Input/Output test by using the Ni MAX an sending ASCII strings to the control unit (after configuring it according to the reference manual), which worked fine. I also used the "jabber"-function of the control unit to send an output string to the PC and was also able to read that string from the buffer. Besides, when I used a LabView-VI to send a command via VISA Write, it also appears on the display of the control (at least the ASCII letters).
Accordingly, I assume that the Serial-to-USB-adapter does work. Is that for sure, or can the adapter evoke any other problems?
However, when I try to use the shipped controlling software, the motor won't work. Furthermore, I contacted the customer support and they sent me some VIs and a LabView-Project, which was tested by the company. Unfortunately, it did not work for me. The motor wouldn't move, when I sent the command, although the LabView-interface indicates that there the connection between PC and controller has been established. As the program has many features and I only need a command to move the motor, read the position and set the origin, I tried to build my own VI. I had a look at some basic VIs for motor control and referred to the manual.
As it seems, the controller uses data streams of full bytes (8 bits, not ASCII) in Big Endian for its strings (I copied the information at the bottom of this text). Thus, I tried to concatenate particular strings to send it via VISA in the correct form (see attached). Do I have to convert the "m" into hexadecimal explcitly? I looked up "Convert ASCII to Hexadecimal", but when I try this, the output string does not change.
However, when I send this string to the controller in normal mode, nothing happens . When I activate the Input/Ouput test (see above), there is a m displayed on the controller unit. So I guess, I am messing up the command structure. Can anybody help me please?
Kind regards
PS: Sorry for cleaning up the diagramm..
PPS: For some reason, I could not attach the VI because " The contents of the attachment doesn't match its file type". So, I changed the name in "-vi" instead of ".vi" as suggested by a forum user. Hope this works for you!
Excerpt form the reference manual:
General Information:
"Command requests are single bytes followed by optional parameters and terminated by a
carriage return (CR, 0Dh). The data stream consists of full bytes (all 8 bits — not ASCII.
The lowest order byte (for example, of the four bytes encoding the X coordinate) is the first
into the controller and is the first out. The default Baud rate is 9600. Commands are
processed bytewise by interrupt and executed only after the terminating CR is received.
There are no delimiters within command strings. The controller will reply with carriage
return (CR, 0Dh) at the completion of normal command processing."
Command structure:
Get Current Position      command ‘c’CR 063h + 0Dh
                                           returns xxxxyyyyzzzzCR three signed long (32-bit) integers + 0Dh
Go To Position                 command ‘m’xxxxyyyyzzzzCR 06Dh + three signed long (32-bit) integers + 0Dh
                                            returns CR 0Dh
Setting up for Serial Communication:
First, use the 9-pin serial port cable provided with the MP-285 to connect the “serial port” of
your computer to that of the MP-285 controller. Next configure your terminal emulator (e.g.,
HyperTerminal in Microsoft Windows (9X and above) to the following settings (or their
equivalent):
• TTY mode
• Echo typed characters locally only (do not echo input to the computer serial port back to
the controller)
• Baud rate to 9600
• 8 data bits, no parity, 1 stop bit
• COM port - set to the port to which you have connected the MP-285 controller
Solved!

Thank you for your feedback!
To make this clear: I dont know if the motor MOVES when sending the appropriate command via MAX. That is because I dont know how to enter the binary? command. I only tried to send some string like "dear moto please move" to see if this ASCII string can be displayed on the control unit while running the input-mode (which I described above).
This works for both, MAX and my Labview-Vi.
However, these are the I/O traces:
1. MAX: I sent the string: "Test"

Problem: Instrument via serial connection

Hello Forum,
I am trying to connect my instrument to my laptop via USB through Serial port. I used NIVISAIC and found the Resource name as ASRL3::INSTR. When I was working with Laview I found the following error
Error 1073807246 occured at property node (arg1) in VISA configure serial port (Instr.). Reason: The resource is valid, but VISA cannot currently access it.
Using the interactive control one of the attribut is in red (Is Port connected: VI_ATTR_ASRL_CONNECTED: Invalid property value
Also when I send Identification query using NIVISAIC, it returns the same command.
I did not understand much of it. However there is a software for the instrument, using which I could connect to the instrument the first time I switch on the system. When I disconnect it and tried once again, it was not connecting.
I had earlier connected Keithley 2400 via GPIB KUSB 488. Is there any problem in connecting two devices. Or is the driver of the software and NIVISA are conflicting with each other.
Please find the screen shots.
Please help.
Thank you.

Hello Dennis,
It did not help much.
7: Write Operation (*IDN?)
Return Count: 5 bytes
8: Read Operation
Return Count: 5 bytes
*IDN?
I tried to query with \n and \r\n; but did no good. There is only one instrument connected to the PC via Serial port.
I would like to know if the identification command is same for all instrument or does it change with manufacturers.
Why does it return the same command that was given to the instrument.
If I am to ignore this, please find the block diagram and manual of the instrument in the attachment. It was said that the commands should be sent as single characters and not as string.
In the block diagram I have used VISA Configure Serial Port, VISA Write, VISA Read and VISA Close vi's. Please tell me whether this is correct. The Commands where given in separate lines or should I use separate VISA Write vi for each characters.
Thank you.
