AT-MIO16-E interrupts on Dos 6.22

Trying to generate an interrupt on the AT-MIO16-E pnp card by using counter G0.
I'm able to program the base address and read port address for the card. I call a InitTimer function
to setup the G0 counter and associated interrupt control logical (Inttst.c). By running the code I can see that
an interrupt is being generated because the Interrupt_A_St bit goes high. However, my interrupt handler
is not being called.
PNP_util.c contains code to initialize the AT-MIO16-E board and IntTst.c is the demo program to
setup the timer and interrupt control logic. I trying to use IRQ5 in the demo code. I setup the pnp by
calling Setup_PNP_Board( 0x240, //board address
0x273, //read port address
5 ) ; //irq
Any help would be apprieated
Thanks

Hi,
Question 1) Why in the world would the TechNet version of MS-DOS be an UPGRADE version??? That makes absolutely no sense at all. Is a "non-upgrade" DOS 6.22 installer available?
>> First of all, MS-DOS is out of life. For the further research on MS-DOS upgrade version, I recommend that you Contact a representative so that you can get the most qualified pool of respondents. Thanks for your understanding.

Question 2) I read that Hyper-V doesn't support MS-DOS. Is this just because there are no integration services for it? I really don't need them for this test.
>> As I mentioned, MS-DOS is too old, it doesn’t make sense to support it on Hyper-V.

OWB10gR2 Repository Browser hangs on report call

Hi,
after weeks of normal work with OWB Repository Browser, it started recently to hang up in the moment when an "Execution Job Report" (in column "Related Information") is called. No difference if error, mapping or workflow process report. We don't know which change in the system may have triggered this. Problem seems not to be in the database (no change in session after clicking the link is noticed). The OC4J windows gives no further log info and I can't find any log file in the J2EE directory. When trying to shut down the OC4J session regularly it brings:
06/09/15 11:41:43 Shutting down...
06/09/15 11:41:45 Thread named: Thread[HttpRequestHandler-3945515,1,ApplicationServerThreadGroup] cannot be interrupted
06/09/15 11:41:45 Thread named: Thread[HttpRequestHandler-30624226,1,ApplicationServerThreadGroup] cannot be interrupted
The DOS box has to be closed the brutal way which recovers after restarting.
some ideas around
regards
Thomas

indeed, it is likely that the report was simply hanging in SQL execution. did you check that before you purged? What can occur is that the statistics for the RT schema get out of whack if the schema is not analyzed. AFter months and months of operations, the execution plan for these reports is no longer valid and ... then you hang for a long time :)
analyze stats. and on slower systems, truncate audit data every now and then. and make sure you aren't running all your mappings in FULL audit mode.
My two cents.

I cannot get innterrupts from an NI6711 analog output board

Hi everybody,
I am using a NI6711 AO board and a NI 6052 MIO board with VxWorks and DDK.
I tried Aoex5.cpp and used IRQ pin 0 and kInterrupt_Output_PolarityActive_Low as
described in the PCI E Series Register level manual since this board
has also a mite chip.
The number of updates is larger than the FIFO size, so that an FIFO interrupt has to be asserted. The settings work fine with an E Series board (NI 6052) but I cannot get any
interrupts on a NI6711 board.
From some posts to the forum I assume that some people got IRQs from a 6711 or similar 6733 board. How did you get them?
Is there a HW problem with the NI6711? It works fine on a Windows computer and LabView examples. I suppose the Labview driver uses DMA instead of board interrupts. Dose the Labview test really tell me something about the IRQs?
Can anybody help? Thanks
Heike

Hi Heike,
I hope this will help you.
I send you two screenshot - one of LabView and one of the DAQmx C Reference help to see the function for cpp.
You can find the "DAQmx C Reference help" on your system:

Ahhhh! good old DOS... so many good programs written at that low level, outside the Windoze environment.Yeah.. cut my teeth on writing code for DOS. Still have all my old BIOS and assembler manuals for it. Wrote my own screen s/w (write to a buffer and then move it into the video buffer, instead of writing char wise to the video buffer via interrupts), mucking about with my own concurrent threading model (using very simplistic cooperative multitasking) and so on. Heck, wrote tons of s/w on DOS... :-)Yeah I've still got a copy of my old machine code programs for writing to buffers and screen memory switching for smooth animation. Run them nowadays and they run like sh!t off a shovel. And all my old coursework including writing an interpreted language and multi-window (dos based windows) editor, parser and the code to execute the language and display the output. Oooo, and so much other stuff.
Awesome back then as you got really intimate with the o/s and hardware. This is sorely lacking today in environments like Java. And I think the reason why so much code written today is less than optimal - to put it kindly.Exactly. Started for me on the Sinclair zx81 (writing Basic), then the Sinclair Spectrum (Basic and Assembly), then Sinclair QL (yes I really had one!) and then the BBC Master 128K (where I got to writing my own rom filing system and creating my own eproms, to integrate with the word processor for additional printing features etc. as well as storing games on rom for speedy loading - and I still have it and it still works!)
It's that level of working with the underlying memory and assembly language that gives you the understanding of how values are passed between code using the stack and registers, and how memory allocation and referencing is done etc. As you say... it's missed in a lot of todays teaching, which just seems too high level and misses the basic concepts of things such as datatypes and why they are different. I bet half the modern programmers wouldn't have a clue how to do multiplication or division of binary numbers using the carry flag.

How can i make the results of dos command print to text area in a gui????

I need to get the results from a command line application to print in a text area located in a gui... i have the following code written, which should run the command... if run from a dos window, the command prints the list of what's in a jar file to the screen.... i want that info that is printed to go in a text area which i have named textBox which is global to the program.. i know textBox.appends() is what i should use but how do i retrieve the info from the dos window to put in the appends method?
The code is below for the method..

DESKTOP SOFTWARE DOWNLOAD ALWAYS GETTING INTERRUPTED

Hello,
I just acquired a Blackberry Torch 9860 and have been trying to download the desktop software to no avail.
The download is always getting interupted with the following message "710_b042_multilanguage.exe download was interrupted. This program is not commonly downloaded and could harm your computer" When I click Resume a SmartSreen Filter Internet Explorer window opens with the message that "this program might harm your computer." When I press Run Anyway another window called 16 Bit MS-DOS Subsystem opens with a message that "The NTVDM CPU has encountered an illegal instruction.....chose to terminate the application.
Please, help.

Hi and Welcome to the Community!
It sounds like you have a computer problem, not a BB problem. Maybe you have some virus protection on your computer blocking this? Maybe something else? It's a basic function...downloading files to your computer. Something on your computer is blocking this from happening, but digging into that needs a computer expert, not a BB expert.
Good luck!

Can i use 6025E card on Dos using Turbo C?

I need to include 6025E card with running program based on turbo C.(Most of the code reletaed to interrupt coming from 4 ports).Can i use NI-DAQ with turbo C"?

Ezi,
You cannot use the 6025E in DOS, because the latest version of nidaq that support DOS is 4.8, and the first version of nidaq that supports the board is 6.5. Thus, they don't match at all. You have to use windows OS, with a C compiler for that environment.
Hope this information is helpful.

Keyboard Interrupt and NI-DAQ

Hi! I have this problem when using an AT-MIO-16E-10:
I made a program in Borland C++ 3.1 that does the following:
-reads in pretriggered mode from an A/D channel (with DAQ_Start);
-when the conversion is done a message is sent to my aplication (Config_DAQ_Event_Message);
- when the message is received by the callback function I do computations with the voltage that was acquired with the DAQ_Start in previous step and the result is sent to a D/A channel (I control a process, and the computations is a numeric PID algorithm).
- all this steps are executed for all datas that DAQ_Start sends to the buffer data. Pretriggered mode is enable and at the end of the main program I have an infinite loop that looks like this:
while(not ESC);
-so the A/D conversions,computations and the D/A conversions are done infinity until ESC is pressed.
The problem is that to notice my application when ESC is pressed I took the keyboard interrupt vector that treats the ESC message. Also in my program I have to change the reference of the process I control; the reference is change also by my keyboard interrupt procedure (if I press '1.0' the reference of the process is a voltage of 1.0V)
Now I get this error when executing the program:
-the A/D conversions are not done correctly (in tests I had values in my buffer even greater 4096, voltages greater then 10V, also a zero is inserted at the even adresses of the buffer - buffer[0], buffer[2], buffer[4]etc. are zero )
-if I don't install the interrupt in the main program and the code of the new keyboard interrupt (declared : void far interrupt my09(void); ) is still in the program (but never used,I don't take the vector interrupt) the result is the same as above.
-when I don't use the keyboard interrupt in my application I I don't put the code of the my keyboard interrupt procedure(the reference is equal with 1.0V in the main program, and I don't change it in any way) the program runs fine and no problem occurs.
Can you please tell what is the solution of this problem? Why can't I have the code of an interrupt procedure in my program?
All the functions that I use in my program are tested and correct implemented. In all other programs that I made, my keyboard interrupt procedure runs without errors and the results are correct. Also this application runs fine if a don't put the code of the keyboard interrupt procedure in it.

Hi again!
Actually I used the "while(1)" loop without using the keyboard interrupt in my application and it worked fine. What I'm confuse about is that even if I don't use the interrupt procedure in the main function and the code of the interrupt is still in my source code, but never used, just code that is never called, because I don't install it, the program gives me the same results as I've explained in the first post, with zeros inserted in the buffer, and voltages greater then 10V.
The timing is not the problem, I can say that for sure, because I've made a tricky one: I installed the keyboard interrupt in another program, that is a TSR. This TSR is activated by the keyboard and it sends all the data I need (in my case: the reference, the ESC fla
g and the CR flag, that memorize if these are pressed) to my NI-DAQ application (I've implemented some code of inter-process comunication). In this case the results are completely the expected one. And this is just because I don't have an interrupt procedure in the same program with NI-DAQ functions.
Neither the interrupt procedure is not the problem, because it's the same in the TSR, and it works fine.
Yet, another program I've done used the timer interrupt, and basically it does the same thing. At every two int 0x08 calls (a sample interval of 110ms) I do this (in the my0x08 procedure):
- AI_VRead...
- do the numeric PI algorithm to the data.
- AO_VWrite...
The result was still the same.
I'm using Borland C++ 3.1 for DOS. Now I'm asking if the problem is not from the compiler. Maybe the segment model I use (although I've tried all of them)or how the compiler is generating the code declared with the prototype:
void far interrupt my_0x09(void);

Interaction with MS DOS-program

I try to interact with a MS DOS-program.
I try something like this:
// start command running
startCmd = "start command";
Process proc = Runtime.getRuntime().exec(startCmd);
istr = proc.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(istr));
printCmdLine(br);
out = proc.getOutputStream();
writer = new BufferedWriter(new OutputStreamWriter(out));
writer.write("second command");
writer.newLine();
writer.flush();
printCmdLine(br);
writer.write("third command");
writer.newLine();
writer.flush();
printCmdLine(br);
// wait for command to terminate
try {
     proc.waitFor();
catch (InterruptedException e) {
     System.err.println("process was interrupted");
// check its exit value
if (proc.exitValue() != 0)
     System.err.println("exit value was non-zero");
The problem is that I can't read from the InputStream:
private static void printCmdLine(BufferedReader br) throws IOException {
     ArrayList list = new ArrayList();
     String outlist[];
     String str = br.readLine();
The program can't read. The DOS prompt waits for an input from the keyboard and nothing more happens. If I don't try to read from the InputStream, the program hangs when it comes to proc.waitFor(); - The DOS prompt waits for an input from the keyboard. I can't achieve this by using a batch file either. Anyone knows how to do this?

1. Buffered reader/writer might not be so good an idea; use the constructor with boolean flush.
2. It might be, that you need to read from the MSDOS program's STDERR, the "error" InputStream. This can be tested in MSDOS by appending to the command-line (NT/2000) greater-than-out.txt and 2-greater-than-err.txt.

Accessing the Control/FIFO registers of NI 8422 in DOS

Using the drivers niboot.exe and ni-pnp.exe driver files we are able to access the COM 1-4 ports on the card as these files create mapping of the COM ports and provides the equivalent base address however the base address of the Control Register, Transmitter/Reciever FIFO register are not specified which is necessary to monitor in order to transmitt/recieve data using the DOS and the code in C.
The solution to look for is either look for the memory/base address of the 8422 card or the function in C language which can access the Control Register, Transmitter/Reciever FIFO register of the card.
Also attacthed an document file for reference.
Thanks

Naru,
The base address of the COM port is necessary in order to determine the I/O address of the registers on the 16550 based UART. For example, the address of the Line Control Register for COM port 1 is calculated by adding the Base Address of COM port 1 + Offset 3. The following is a table that gives the offset of each register. You can obtain more information by downloading the datasheet of the UART used by the 8422 at www.exar.com (16C654).
Register Offset
RX Buffer 0
TX Buffer 0
Interrupt Enable 2
FIFO Control Register 2
Line Control Register 3
Modem Control Register 4
Line Status Register 5

Waiting a Dos Command?

Hi;
In one of our projects, we have to call a dos command in java. That seems ok however there is a problem about code. It gives an exception because the remaning program goes without waiting the dos command's completion.
Runtime r = Runtime.getRuntime();
r.exec("cmd /C sort 1.txt /O 2.txt");Above code, makes a sort in 1.txt and saves it to 2.txt.. My code goes without waiting the 2.txt to be created and gives an exception like couldn't found 2.txt . Thanks for any help, i hope i could explained clearly what i wanted to ask..

Yea you're right thanks for answer. But yesterday Petter a.k.a wildfrog from Codeguru forums posted this solutions. Anyway i'm putting it here if someone needs it.
To wait until the 'child process' has completed, you can do something like this:
Runtime r = Runtime.getRuntime();
Process p = r.exec("cmd /C sort 1.txt /O 2.txt");
// wait for it to complete
try
p.waitFor();
} catch (InterruptedException e)
// wait was interrupted

>I kind of like an indicator that acknowledges something is happening.
Agreed! Much as I love Firefox, I hate it's lack of a splash screen. Every single program on the planet that has a GUI should have as it's very first action when started to show a small splash screen, just so the user knows the command to start has been accepted. This action should be set to High Priority, interrupting all other actions such as virus scans, other programs closing, downloads, file copies, etc. Once the Splash loads, the rest of the start-up process can return to Normal priority and load in it's proper OS managed sequence.
I can't tell you how many times I've accidentally ended up with three or four browser windows open because there's no indication that anything is happening.

How to change soundblaster PCI64 IRQ for DOS - win98

Running Windows98se, recently added wireless Zonet adapter for internet capabilities. MSDOS games (DOS/4GW) requires sound card IRQ 7 or lower. My IRQ's are as below. Note: I have no manual for the creative Labs Soundblaster PCI 64 card(IRQ 0) or, Ensoniq Audio legacy Device. Tried device manager and sysedit changes without success. DOS games video is OK but no sound, nor will the in-game sound card configuraton work. How do I change its IRQ to 7 or below? I have no printer on the computer.
0 System timer
Standard 0/02-Key or Microsoft Natural Keyboard
2 Programmable interrupt controller
3 Telepath 56K Voice Faxmodem PNP
4 Communications Port (COM)
5 802.g/b Wireless LAN Client Adapter
5 IRQ Holder for PCI Steering
6 Standard Floppy Disk Controller
7 Printer Port (LPT)
8 System CMOS/real time clock
9 Matrox Millennium G450 DualHead
9 IRQ Holder for PCI Steering
0 Creative Labs Sound Blaster PCI64
0 IRQ Holder for PCI Steering
Intel 8237AB/EB PCI to USB Uni'versal Host Controller
IRQ Holder for PCI Steering
2 PS/2 Compatible Mouse Port
3 Numeric data processor
4 Primary IDE controller (dual fifo)
4 Intel 8237AB/EB PCI Bus Master IDE Controller
5 Secondary IDE controller (dual fifo)
5 Intel 8237AB/EB PCI Bus Master IDE Controller

Try another PCI Slot, or set IRQ 0 as RESERVED in BIOS Plug&Play configuration. Make shure you installed the dos-drivers correctly. Set the soundblaster variable correctly. And dont expect a PCI card will work with your dos-games. You will need an ISA card for 00% compatibility because: It doesnt need drivers, Dosgames will have its own, and: the card is directly accessable.
