Parallel port under linux

could anybody help a linux-labview beginner?
i'm trying to write to my parallel port. but labview is obviousely not set
up for this. does anywone happen to have a vi which can do that?
best of regards

Michael,
So using an true ASCII printer or dircetly /dev/lpx is the easiest
solution. Just "print" the ASCII charakter representing the bits to
set.

Parallel Port under CVI

Hi,
is it possible to write to the parallel Port or to other
adress ports under Win95 or WinNT with CVI ?
Do you know a good book about that subject ?
thanx.

Yes, CVI has a kernel mode driver (cvintdrv.sys) which loads automatically when the CVI environment starts. It enables Port I/O under NT (95/98 aready allows it)

Help needed urgent please ( parallel port access in linux)

hi all, i am trying to read and write data to /from the parallel port , i am running IBM j9 vm on linux.under /dev there are lp0..lp3 parport0..parport3, and port devices , i dont know which one to use , i have tried all , they all return with an ioexception saying "cannot find the file" except for port device which does not generate any error but it does not return what i have written on it ,
any help would be much appreciated.
i am using fileoutputstream and printwriter calsses .
i dont want to use javax.comm api cause i think its incompatible with ibms visual age micro edition ( the one i am using ) so i would prefer something that works with my IDE .
thanks

However, there is an on-going OpenSource version called "RXTX" (http://jarvi.ezlink.com/rxtx/) that works quite well. Be sure to read all the documentation that comes with it, as you'll need to set some permissions on the ports you want to use.

Linux parallel port

Dear All,
is it posible to read and write registers in the io address space under linux. I want to use the parallel port to turn on/off some LEDs and check the state of several switches. I have done this with windows 2000, but i cannot find any solution for linux.
cheers,
Frank

There are several solutions for your problem. The most simple is to create a shell script that control the state of the parallel port and call "execute" from LabVIEW.
Using http://parashell.sourceforge.net/ is simple: (http://parashell.sourceforge.net/docs/parallel.txt)
----- How to use the program -----
parashell is a very easy to use program. The program takes two parameters, the Parallel port to send the data to and
the data value to send. That value must be integer in decimal format (for example 255). Hexadecimal
numbers can also be used, but they must be preceded by 0x (for example 0xFF). The program uses very little error
checking to keep it simple.
Example how to use parashell.
parashell 0x378 0
Set all datapins to low level.
parashell 0x378 255
Set all datapins to high level.
parashell 0x378 1
Set datapin D0 to high level and all other datapins to low level.

Is it possible to get direct access to parallel port pins under Windows NT? What can I do

to get such an access under NT? I found Write to Parallel Port.vi but I can`t open it. The error that occurs is:
resource not found, error occured while loading the vi, labview load error code 8: could not load vi ressources.
This vi is from 1994. Maybe the source of trouble is that I`m using version 5.1.1 or it is a problem with NT. What do you think?

Parallel Port.vi can only be used in DOS-Systems (like Win9x, WinME ;-). NT does not allow writing to parallel port with low level routines. It is more useful to use the digital port that is on most of the DAQ cards.
Some more informations on parallel ports: http://www.lvr.com/parport.htm
In general it seems to be possible. Somebody told me just to use the write port command with the address of the parallel port. Another way seems to be to tell NT to allow direct port access - but I don't know how.

Parallel Port Help. Please

Dear friends,
Am developing an application that is to use the javax.comm package under a Linux (Fedora Core 5) system. However am quite stuck when it comes to sending a signal to a specific 'wire' off the parallel port.
I have read about the configuration of the parport that is in such a way:
1      Not normally used
2-17      Data ports
17-25     Ground
so that if I want to send a signal to port 2 and ground I will open the port and transmit the signal 0100000000000000000000000 correspoding to the various port wires. This is, however, not working since the ports are giving me a HIGH signal through the entire time even when no signal is being trandmitted. How can I work around this or is there an easier or better way to go round this?

After much googling and searching all over the web, I found out that package javax.comm is just redundant and, for a lack of more appropriate word, useless. The same goes for package rxtx. However, I came across something called parport that gives excellent output in very simple ways :)

K9A plantinum and Parallel Port. [closed]

Greetings,
I'm wondering bout the parallel port settings in the bios.
What settings are recommended for Vista 64. I've tried most "common" settings without luck. :(
I've been trying to get my hp2100 to function under vista and linux, but just cant get it to operate.
I'm starting to fear a defective MB. In fact vista has been terribly unstable on this system.
I've verified the RAM with memtest.
I've had the printer functioning perfectly on a prior computer. Normally windows auto detects the hp 2100. I get nothing from vista.... thought the hardware manager does say the LPT for is operational.
comments? Suggestions?
Thanks

Any answers to those?:
Quote from: Bas on 16-December-07, 09:39:26
What HP 1200 might this be?
LaserJet, DeskJet, what???
HP has hundreds of devices that have the number 1200...
What you have tried from those and what are the results?:

"Next I tried ECP DMA 1 This also did not detect the 2100 but I was able to finish the wizard, but alas I was still unable to print. Testing the printer stated that the test sheet was sent, but the printer never responds."
Check printer cable connections, try change printer port, switch to EPP+ECP.

Failed to install enterprise manager under linux

When I installed Oracle 10g(10.2.0.1) under linux, I got an error when running
/ora01/db/oracle/product/10.2.0.1/bin/emca within oracle universal installer.
The emConfig.log file shows such error:
oracle.sysman.emcp.exception.EMConfigException: Invalid value null for parameter PORT
at oracle.sysman.emcp.ParamsManager.checkParam(ParamsManager.java:2630)
at oracle.sysman.emcp.EMDBPreConfig.checkConfigParams(EMDBPreConfig.java:1285)

at oracle.sysman.assistants.util.em.EMConfiguration.run(EMConfiguration.java:426)
at java.lang.Thread.run(Thread.java:534)
So I have to run emca after the oracle installation. I am new to this tool. I modified both tnsnames.ora and listener.ora file to set port to 1521. And then I run emca -config all db,
but now I cannot pass "entering the password for SYS user" (I already set SYS user's password to oracle, and it works when using sqlplus.) .
I am totally confused. What should I run emca to set up the enterprise manager's website? Now I can use localhost:5560/isqlplus and localhost:5560/isqlplus/dba.
Many thanks!!

I just run emca as oracle instead of root, then the password got passed, but I got new errors:
Aug 30, 2007 5:59:59 PM oracle.sysman.emcp.EMConfig perform
SEVERE: Failed to allocate port(s) in the specified range(s) for the following process(es): JMS [5540-5559],RMI [5520-5539],Database Control [5500-5519],EM Agent [3938] | [1830-1849]
What should I do? Is running emca -config all db necessary to get enterprise manager installed?

Using XP software with a parallel port dongle in windows 7 professional

Please help... Looking to have my parallel port dongle recognized for my older version software (XP) in Windows 7 under the XP PC mode. Help in figuring out if LPT1 is set correctly or what I am doing wrong.
Thanks

Hello,
I have W7 Professional 64 bit with Windows Virtual PC/Windows XP Mode installed. I have some older programs installed in XP Mode and they are working properly.
Unfortunately, I have one older program that I currently have working on an older XP Machine and that program requires a Sentinel dongle to be seen on the LPT1 Parallel Port. Since my W7 computer has an LPT1 Header on the mother board, I have purchased and
installed a PCI-Express Parallel Port and I have the ribbon cable connected to the LPT1 Header.
After I enabled the parallel port in the bios, I could see LPT1 in the W7 Device Manager and in the Windows XP Mode Device Manager. However, when I click on
Windows Virtual PC, highlight Windows XP Mode.vmcx and click on Settings, LPT1 does not appear.
I have installed my old program in Windows XP Mode and it starts to run but, when it gets to the point where it must see the Sentinel dongle on the LPT1, the
program does not find the dongle.
I also purchased a Manhattan MHUSB to DB25 Parallel Converter and plugged it in. It said that it found new hardware and installed drivers for it but that didn’t
work either.
I am not married to any particular solution. So, I would use a USB Adapter or LPT1 connected to the mother board but there must be some code editing or changes
in settings to make the dongle work in XP Mode.
Can you tell me how to get W7 Professional 64 bit with Windows Virtual PC/Windows XP Mode to find the Sentinel dongle
on LPT1?
Thank you,
Dan

Problem in sending data to parallel port

Hello,
I can open a parallel port (LPT1) using java comm api i,e javax.comm.
but problem in sending data to parallel port,
I choose the appropriate port(LPT1), it is in bi-directional mode according to BIOS configuration.
but according to the java program the mode is SSP.
when i write data to parallel port the volt-meter give a reading of high state for all data pin (pin1 to 9) i,e the parallel port doesnot change state. I am using windows XP.
What is the solution?

try it on Open Solaris 10 or Linux platform.
also just try using the new FileWriter("LPT1").write("Hello");
on windows platform

Shell script to start, stop and restart a JAR under linux

Hi everyone,
Does anyone have idea to write a shell script to start, stop and restart a JAR under linux? it can also indicate a method or parameter? Thanks!
this JAR inculdes a class with main method like this:
public class Client(){
public Client(String name){
public void stopClient(){
public static void main(String[] args){
new Client("/tmp/text.log");
}

Does anyone have idea to write a shell script to
start, stop and restart a JAR under linux? That part isn't really clear.
Start would be java -jar myjar.jar.
Stop could either be kill, which kills the whole process; kill -TSTP, which suspends the process, or some application-specific communication such as sending something over a port; or putting something into a file or something.
Restart could just be the same as start (if stop is just kill); kill -CONT, if stop was kill -TSTP; or some other app-specific communication.

NI-VISA step by step configuration under linux

Hi!
I need to connect and acquire a codebar reader connected to RS232.
I have: P4 2.4GHz with PCI6023E, mdk 9.1, LV 6.1 comedi, nicvirte and nivisaserver - nivisa drivers correctly installed and running. Serials RS232 are named ttyS00 and ttyS01 under /dev. devfs is running.
Q:Which name belongs to ttyS0x under linux?
Q:There are some literature on this arg?
note: running "find Serial ports.vi" and probing "VISA find resource" icon the result is:
'ASRL1::INSTR' (=> ttyS01?)
Well, trying to read a barcode, with 'LabVIEW <-> Serial.vi' i have no error and no reading. note cpu load for lv process go to 99%!
Any advice?? thanks in advance!
tetractis

Hi,
I find a few things strange here. First normally linux distributions name the serial ports ttySx (where Com1 == ttyS0, Com2 == ttyS1, ...).
Is this just the way mandrake sets things up or is there somthing else at play here?
Secondly make sure that you have +rw permissions for the ports you are trying to get at.
You may also want to test functionality by using something like minicom to test that the data is comming into the port and being transmitted/received correctly.
Hope this helps out!

Different behaviour of file vis under linux and microsoft

I am porting software written under Windows labview to Linux Labview (6.1). When using the Open/Create/Replace vi in windows if I use a pattern of "*.abc" and enter "123" in the dialogue box a file called "123.abc" will be created which is what I would expect. The same operation under Linux will create a file called "123" without the extension. Is this normal and is there a way of making the linux version behave in the same way as the windows version?

Sorry about the delay - vacation.
There appears to be no check box under Linux to use native file dialogs although it does indeed exist under windows. In fact the linux version does use linux file dialogs by default. It seems that the only options are to force the windows version to behave like the the linux version - which is counter intuitive, or write a new file dialog vi for linux.

The problem only appears using JDK or JRE 1.6 32 bit edition on a Linux 2.6 x86_64 kernel in VMware. Tests using real hardware, using a i686 kernel and using JDK / JRE 1.6 64 bit edition or JDK / JRE 1.5 (32 bit and 64 bit) could not reproduce the crashes.
Questions:
- Is there a general stability problem when starting the 32 bit Java VM under Linux 64?
- Does anybody have similar problems with
- Java VM 32bit under Linux 64?
- Java VM in VMware (both ESX and Workstation)?
Simple stress test application:
public class GCStress {
private static Thread[] threads;
private static java.util.Random random = new java.util.Random();
private static int maxBytes;
private static int numThreads;
public static void main(String[] args) {
numThreads = Integer.parseInt(args[0]);
maxBytes = Integer.parseInt(args[1]);
threads = new Thread[numThreads];
for (int x = 0; x < numThreads; x++) {
threads[x] = new Thread(new Allocator(), "Thread_" + x);
threads[x].start();
while (true) {
for (int x = 0; x < numThreads; x++) {
if (!threads[x].isAlive()) {
threads[x] = new Thread(new Allocator(), "Thread_r" + x);
threads[x].start();
try {
Thread.sleep(500);
} catch (InterruptedException e) {
// ignore
private static class Allocator implements Runnable {
public void run() {
while (true) {
int tSize = random.nextInt(maxBytes);
// System.out.println(Thread.currentThread().getName()
// + " allocating " + tSize / 1024 + "kb");
byte[] tMemFiller = new byte[tSize];
try {
Thread.sleep(random.nextInt(200));
} catch (InterruptedException e) {
; // ignore
}

The program is started like this:
./jdk1.6.0_06/bin/java -server -Xms32m -Xmx256m GCStress 500 10485760
And I run it usually 5 times in parallel. 1 time seems not to be enough (I should test that tonight).
However, I've tested using several -XX: flags, but nothing really helped! (-XX:+UseParallelGC, -XX:-UseTLAB, -XX:+UseSpinning -XX-UseThreadPriorities, -XX:-UseBiasedLocking, -XX:-UseLargePages)
