X4100 (x4200) system console on rear serial port ?

I have a number of x4100's and would like to have the bios appear on the serial console at the rear of the device rather than the IOLM interface. I am happy to only access the IOLM interface through the ssh interface. i.e. how to i redirect the bios console on boot to the rear console port ?

The BIOS contains an option for "Console Redirect". It is typically OFF by default. If you set it ON, then power cycle the system, the BIOS screen will appear on the attached terminal. Make sure to set the baud rate properly... it should be 9600.
Have you tried hooking a console to the serial port? On some BIOS versions, "Console Redirect" is set ON by default.
The kicker here, obviously, is that if the default for this option is OFF, you have to attach a graphics head to the graphics port of the system as well as a USB keyboard to get into the bios and set console redirect to ON. There is no getting away from the fact that these Galaxy class systems use PC motherboards, albeit ones beefed up for SUN's needs.

Svc:/system/console-login:default failed repeatedly

I am in desperate need of help. I installed some patches from Sun Update Manager and rebooted as instructed. My system comes up but when I tried to login through the console, the login prompt keeps coming back, thus no users can log into the system. I even tried to ssh into the system and when I enter my username and password, I get a blank screen and cannot do anything.
I use a laptop to access the system through a hyperterminal serial port and when I navigate through directories as root, I cannot run ls commands or more on files. I do see an error message using the ls command:
ld.so.1:ls: fatal: libsec.so.1: version 'SUNW_1.2' not found (required by file /usr/bin/ls)
open failed: No such file or directory
Killed
When I use the svcs command, I see that the svc:/system/console-login:default is on maintainance. I disabled it and tried to enable it again, but the service stays offline. I tried all kinds of svcadm commands to get the service running, but nothing works.
I also tried killin the sulogin so that the sulogin service becomes disabled and enable system/console-login, but that didnt work either.
I tried using the svccfg steps, nadda. Can someone help? Thanks.

Labview needs 2 goes to start the serial port

Hi,
When I use Labview with the serial port handlers, beit VISA or the
serial routines, I always have to run my external device
(microcontroller based system connected through the serial port) and
then run Labview but the first time I run it it never works. I then
need to reset my microcontroller system and run my Labview program
again and it runs fine, and every time after that.
Has anybody else noticed this and what can I do to fix it?
Ken

Your statement "it never works" is kind of vague. How doesn't it work? Do you get an error, garbage data, no data, or what? Is this system always spitting out data that needs to be synchronized? When you have it working, stop the LabVIEW program and restart it right away, do you have the same problem or do you only see it after stopping the system and restarting it? Aside from recomending that you do a flush of the serial port buffer before sending and receiving data from LabVIEW, more details would help to provide some sort of solution.

Fieldpoint serial port communication?

Hi,
I am a researcher from School of Biotechnology, Dublin City University, Ireland. I have been using Labview programming (version 8.2) for bioprocess monitor and control. I am using Fieldpoint (FP2010) module for data acquistion and control. I've connected analog outputs from various controllers to appropriate channels and found data acquistion working fine using respective VI's. We have few instrument outputs which are need to be connected through serial interface on filedpoint's serial port. We are using a multiplexer (B & B electronics) for channeling all serial outputs (of instruments) to serial port of Filedpoint. VI's developed for all serial interface of multiplexer ports found working (data logging ok!) , when it is connected directly to COM1 port of PC. But when multiplexer serial interface is connected to serial port of Fieldpoint, the data values fails to log on the PC. Ethernet cable is used for interfacing filedpoint with PC. It seems the PC recognises COM1 port for serial interface but not serial port of Field point.
We have a driver software for multiplexer, where we already configured all serial input and output ports as required. How to configure PC to serial port present in Filedpoint instead of it using COM1?
I tried playing with MAX configuration as wells device manager of PC, but system couldn't recognise serial port of filed point.
kindly provide me a solution.
Thanks

Senthil

Hi,
There is a software component that normaly would provide the feature you are looking for. It is the VISA Server. Unfortunately this component is not installable by default on cFP 20x0 controllers because of memory limitations.
Your controller has enough memory, so you could try to install the Server by hacking the driver installation configuration file for the NI-VISA server. Keep in mind that this is not an official feature and the usability could be limited.
Go to your   \\Program Files\National Instruments\RT Images\NI-VISA Server\4.x    folder and open the "install_81xx.cdf" file with your wordpad.
Add the bold line to the file as shown below:
<?xml version="1.0"?>
<?CDF VERSION="1.1"?>
<SOFTPKG NAME="{E62A7BA2-8ED9-4C4A-AFA1-0DE33A188D61}" VERSION="4.4" TYPE="VISIBLE">
    <TITLE>NI-VISA Server</TITLE>
    <ABSTRACT>Remote VISA Server -- Shares VISA resources over the network.</ABSTRACT>
    <IMPLEMENTATION>
        <DEVICECLASS VALUE="PXI"/>
        <DEVICECLASS VALUE="Desktop"/>
        <PROCESSOR VALUE="7002"/>
        <PROCESSOR VALUE="7063"/>
        <PROCESSOR VALUE="7151"/>
        <PROCESSOR VALUE="7175"/>
        <PROCESSOR VALUE="E002"/>
        <PROCESSOR VALUE="E001"/>
Save and close the file and close and reopen MAX. Go to your remote target and open the software installation tool. Now you should have the VISA server as an option for installation.
After installing it and reboot, go back to your remote target in max and go to Software/NI-VISA 4.x and choose VISA Options at the right page. Go to Aliaes and choose "ADD Alias".
Now enter ASRL1::INSTR into "Ressource Name" and "COM4" as Alias name for example. Now go to VISA Server /Security and add a * to allow access for every Host connected to your target.
Save your settings and change to MySystem/Software/NI-VISA 4.x and go to VISA Options at the right page. Go to Aliaes and choose "ADD Alias".Now enter visa://your remote IP address/ASRL1::INSTR into "Ressource Name" and "COM4" as Alias name for example. Save your settings.
Now you should be able to access your remote COM4 interface from your HOST, by using the COM4 alias within the VISA ressource control.

Using Serial Port as Console (not Mac OS X Server)

Folks using other Unix-y operating systems, as well as Mac OS X Server, can use a terminal plugged into their machine's serial port as a console to access the shell. I've searched high and low for a way to do this with regular Mac OS X Leopard with no luck. None of the solutions for Linux/*BSD/etc... work.
Any ideas?
(FYI: I'm using a USB to 9pin RS-232 cable. I've confirmed that my Mac can talk to the machine attached via this interface.)

I fixed it. It turns out that the Leopard -> Snow Leopard Migration screwed up the Subversion repository various credentials for user/group and other during the migration copy. Fortunately I had "cloned" my entire Leopard disk. I copied the cloned repository into the Snow Leopard disk and everything works. It looks like this was the fault of the Apple Migration process.

I pull fiftyfour bytes of data from MicroProcessor's EEPROM using serial port. It works fine. I then send a request for 512 bytes and my "read" goes into loop condition, no bytes are delivered and system is lost

Hello,
You mention that you send a string to the microprocessor that tells it how many bytes to send. Instead of requesting 512 bytes, try reading 10 times and only requesting about 50 bytes at a time.
If that doesn�t help, try directly communicating with your microprocessor through HyperTerminal. If you are not on a Windows system, please let me know. Also, if you are using an NI serial board instead of your computer�s serial port, let me know.
In Windows XP, go to Start, Programs, Accessories, Communications, and select HyperTerminal.
Enter a name for the connection and click OK.
In the next pop-up dialog, choose the COM port you are using to communicate with your device and click OK.
In the final pop
-up dialog, set the communication settings for communicating with your device.
Type the same commands you sent through LabVIEW and observe if you can receive the first 54 bytes you mention. Also observe if data is returned from your 512 byte request or if HyperTerminal just waits.
If you do not receive the 512 byte request through HyperTerminal, your microprocessor is unable to communicate with your computer at a low level. LabVIEW uses the same Windows DLLs as HyperTerminal for serial communication. Double check the instrument user manual for any additional information that may be necessary to communicate.
Please let me know the results from the above test in HyperTerminal. We can then proceed from there.

Serial port for console access to switch

Just got a Netgear L2 Switch, and need to use VT100 terminal emulation to connect to the switch's serial port.
Does anyone know how to enable the Xserve's serial port for this type of job? When running Zterm for OS X I get an "Error: 16 opening port" and I'm at a loss for how to do it. I've heard that USB to Serial adapters have been working, but it seems silly that the serial port wouldnt work.

Thanks Camelot, your advice was spot on.
Just to close the topic:
Edit "/System/Library/StartupItems/SerialTerminalSupport/SerialTerminalSupport"
and change the line:
ENABLESERIALTERMINAL=$TRUE
to
ENABLESERIALTERMINAL=$FALSE
also, may be redundant with the last step but I edited /etc/ttys and changed:
tty.serial "/usr/libexec/getty serial.9600" vt100 on secure
to
tty.serial "/usr/libexec/getty serial.9600" vt100 off secure
Finally, dont be an idiot like I am, and leave the XServe case lock on... this will prevent the port from operating, and cause you to go crazy.

Com,unicting on Serial Port using RXTX on Mac System!

Hi,
I have written an application which acts as an interface between the GPS device and Mac System. I have used rxtx api for communicating on Serial Port. The communication works well for some time. This device gives NMEA output and its proprietory sentences as output too. It is a GPS data Logger. I have to pass different commands for communicating. For instance for login purpose I have to pass the command $PLSC,231,1*FF. And on passing this command the device stops giving NMEA sentences. And responds back with $PLSR,231,1,1,00000000,GPSLOG*33. Sometimes this output and NMEA output both gets mixed up such as $PLS,$GPRMC,00000GPS,,,,.
The devices windows application which is not developed in Java works fine. Is it the problem with Serial API or some other issue. The device operates at 4800 baud rate.
Can anyone over here help me out?
Thanks & Regards
Sunil

This is just a shot in the dark.
Try right-clicking on the VISA write and select "do I/O syncronously".
If this works, please let me know. I have been trying to figure a good reason to do serial I/O "syncronously" but was not able to come up with one until I read your question.

Serial port for an alarm system

I have an alarm system set to receive inputs from LabVIEW-controlled digital I/O cards. All the digital ports are fully utilized for data input. When an alarm state is reached, we would like to use the serial port to relay the alarm condition to a global monitoring system. I don't know if the serial ports can accomplish this as the global monitoring system typically looks for a dry contact or a relay to be tripped. What are the capabilities of the serial port along these lines? Can I have it set to constantly send a 5V signal of dummy data and then drop that data transmission when the alarm condition is reached?

RS-232 can be +-12V or more depending on how the physical drivers are configured. However, if you can handle these voltages, then you can simply assert or deassert one of the modem control lines (RTS or DTR) to indicate your alarm state. If you want to use the TX line, you can set and clear the break condition. If you hook up a multimeter to one of these signals and experiment with NI-VISA in LabVIEW, you should be able to create a signal that will work in your system.
However, if you need +5/GND, you can use an RS-485 port which generates (well, in a way) signals between 0 and 5V (or 0 and 3.3V depending on the system). RS-485 is a differential signaling system, but you can just throw away one of the lines. In this case you'll use TX+, TX-, RTS+, or
RTS- depending on what you need.

LV acquire the print information from the embed board with Linux system through serial port

I want to acquire the print information by LV from the embed board with Linux system through serial port, like the window hyperterminal tool?
I try to use VISA serial config function to achieve it ,but lost and prompt that is error like attachment.
I can't sure that my idea is reasonable.
help me
thanks a lot!

I ended up finding the answer to my problem. After pointing a client directly at one of the DPS systems, I saw the following error in the logs:
[27/Jul/2009:17:11:47 -0400] - OPERATION - INFO - conn=3688 op=4 BIND RESPONSE err=12 msg="The server is not configured to pass through control 1.3.6.1.4.1.42.2.27.8.5.1" etime=0After adding that control OID to the allowed-ldap-controls, I could login via password auth. Adding this control also allowed for password changes to work from a client system.

Xserve serial port console

I'm considering ordering an OpenGear console server to connect to our Xserve, for access via the serial port. The Xserve User Guide says (pg 20) to set terminal software to 56KB/s, which translates to 458 752 bits per second. The console device that I'm considering:
http://www.opengear.com/product-cm4001-spec.html
...does up to 115 200bps. My question is: can the Apple serial port scale down to more standard serial communication speeds?

You're misinterpreting the docs. The default speed it 56kbps, or 57,600 bits per second, well within the limits of the unit you're considering.

Using a PS/2 keyboard on a Sparc workstation through the serial port

We have recently migrated an application that used to run on a PC, to now run on a Sparc Workstation. This is a SunBlade 1500, running Solaris 8. The application is running in a dedicated console which has a fitted keyboard and trackerball that have PS/2 connectors and cannot be changed.
We need a way of connecting the PS/2 keyboards to the serial ports of the Sparc workstation. We already have a piece of software that will read ascii values from the serial port so we definately want to go through the serial ports.
Can someone please suggest what converters will be required to get the output of the keyboard and trackerball as ascii input to the serial port.

Actually, that's not a bit perverse, at all.
Jonathan's suggestion is a standard method of connecting to a server.
(null cable between the computer serial ports)
... see the Solaris man pages.
man tip
TeraTerm and Hyperterminal are customarily used on a PC running some dialect of Windows.
The 'tip' command is all that's necessary between Solaris systems.
PS/2 is not a serial connection, but is a keyboard/mouse interface 'invented' by IBM when they offered their XT-class PS/2 line of desktop systems, back in the 1980's.
I found this next link by using Google:
http://members.chello.at/theodor.lauppert/computer/ps2/
The smaller DIN ports were more compact than the AT-class keyboard ports and the mouse moved from a serial port to a dedicated mouse port.
Serial communication devices are not keyboards, per se,
and keyboards are not serial communication devices.
You need other hardware in between to translate what the human being sends, and another computer is a common method to accomplish that translation.
Having said all that ...
Since you cannot change the dedicated console hardware,
I suggest you go to the manufacturer of that console equipment
and have them suggest some sort of serial-to-serial interface lash-up.

Using a serial port under j9.. How?

I am trying out j9 on an ipaq. I am trying to get javax.comm to work.
When I call CommPortIdentifier.getIdentifiers ();
I get java.lang.string.NoSuchMethodError: java/lang/String.<init>([BIII)V
It would appear that the javax.comm package was implemented using a now deprecated String method, and that IBM has chosen not to implement deprecated methods in it's j9 vm (I get the same issue trying to run swing.)
One would think that what is needed is an updated javax.comm package. However, there doesn't appear to be a javax.comm package on Sun's site, let alone an updated one. Whats going on here? Can someone give me an idea of how Sun and/or the JCP thinks about developers who want to use serial ports?
Is there a workaround? A different way of talking to a serial port? Or should I abandon j9? I should add that I got my software running just fine on nsi.com's creme vm (javax.comm and swing too) and it worked without any hassles. It even understands jar files (is there a reason why IBM insists on having a link file?). However, the reason I persevered was that a) j9 is cheaper and more importantly b) nsi.com don't seem terribly keen on actually selling their product. I have lots of references to them selling their vm in bundles of 40 ($1000) which is a bit ouchy but hey I'm not paying for it. But, you'd think the nsi.com people would actually confirm this on their site?
So.. can it be done? And why, in the world of embedded systems (my field) and now lots of phones and pdas, is so little attention given to the humble serial port? It doesn't matter how fancy the protocol is, underneath it all is a UART. grumble

Hi Russel,
I will probably soon be in the position you are in trying to get this to work. I found the following page which offers some promise.
