Serial Port Communication Asp Net

In addition to this, each serial communications device needs an interrupt request number (IRQ) and these numbers are limited in a PC. The end result is that although things look okay, you may still be having trouble with your communication port. On most desktop PCs, you will find two serial (COM) ports. Older systems often have one 9-pin serial. We introduce in this paper, to the best of our knowledge, a new approach to perform serial port communication on client devices from a dynamic web application implemented using ASP.NET.

serial port communication
Hi, I am trying to figure out how to use the serial port in perl. I am using windows with ActivePerl. This is what I have so far: [CODE] $o_rs232Port = new Win32::SerialPort($ARGV[1]) || die 'Can't open $ARGV[1]: $!'; $o_rs232Port->user_msg('ON'); $o_rs232Port->baudrate(115200) || die 'Can't set 115200'; $o_rs232Port->parity('none') || die 'Can't set parity none'; $o_rs232Port->databits(8) || die 'Can't set 8 data bits'; $o_rs232Port->stopbits(1) || die 'Can't set one stopbit';...
Serial port communications?
I would like to open a serial communications port directly in PB script. I am currently using PB 6.0 and do not see a way to do it without using an .ocx or .dll. I there a way to open a comm port directly in PB and perform simple input/output operations to this port? I have tried without out success to use PDQComm .ocx. I am not sure how to reference the PDQComm.ocx ole object in PB. Plus, I don't have a big budget on this project to buy the 3rd party control. Any help would be appreciated!! I have used the Serial drivers from Willie's Computer Software Company (W...
Serial port communications
Hi All I am currently using async pro for serial comms, but due to lack of updates/support I would like to move to another comm component. I am currently looking at TComport. In async pro, I bypass the events and send-wait-receive the data. The data sent, is a sequence of integers, sent from an array and received back into an array. Is this possible with TComport or is there a better way? Some code would be appreciated.

What are the options available for PB developers for serial port communication? I browsed the web and found I/O ActiveX Communications Control from JSPayne which is well documented and not that expensive (70$), but takes almost 2M of space (the ocx takes only 48k, other files take the rest) and requires registering during setup. Is there anything smaller out there? Thanks!

Communicating with the serial port
Hi, i would like to know in general how it's possible to communicate with the serial port with Powerbuilder. In particular i would like to know if i have to use the Windows API or if there are OCX/ActiveX that can be used to perform this task. Thank you very much, Antonio. -- Antonio Volpon - http://laika.nline.it/users/volpon/ mailto:volpon@nline.it Hi, there is an OCX which comes with VisualBasic a microsoft product. MSCOM32.ocx. That would do it. It ONLY works on PB6. HTH Sanjay Antonio Volpon wrote: > Hi, > i would l...
Communicate with Serial Port
I am working on a project which is using a digital scale and connect it to a com port. Then using PB to send a command to the scale and the scale would then send back the weight reading to PC. My question is what is the easiest way to do this in powerbuilder. I know in VB I can call open function to open the com port. However, PB is my favour and I don't want to change to VB. I am not familiar with windows API or DLL call. Can anyone help me! Thanks Simon I would guess that Win APIs would be your best bet. perhaps these will help. http://www.vbapi.com/index.html http:...

Serial Port Communications #2
Hi all, I am able to write to a com port just fine. The problem that I am having is reading from a COM port. Here is what I am doing. I open the com port for write (because I have to send a esc code to the device first). I then issue the ReadFile function. I am not sure if I have the read function defined correctly or if I am calling it correcly. My external Functions are defined as follows: /* To create a file */ function long CreateFileA(ref string lpszName,long fdwAccess,long fdwShareMode, long lpsa, long fdwCreate, long fdwAttrsAndFlags, long hTemplateFile ) library &q...

Communication using serial port
Friends, How can I do in P++ 2.0 write and read operations in a serial port ? I need to send a string or a sturcture from a computer to other. I used the CreateFile(API 32) to open the port. The funcion WriteFile / ReadFile (API 32) don't work fine. Any sugestion will be wellcome.

Serial port communication Application. Let see an example code where I am talking with a Mega2560 Arduino device. I have written a small code for mega2560 in which it receives serial data. If received data is “aticleworld” then it will send a message “Welcome to AticleWorld!” or otherwise it will send the message “Please Send Correct. In computing, a serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. This is in contrast to a parallel port, which communicates multiple bits simultaneously in parallel.Throughout most of the history of personal computers, data has been transferred through serial ports to devices such as modems, terminals, various. My asp.net application has to connect to a serial port to get weights occasionally. But since its not possible to do this directly from ASP.net, I am using a WCF service. How do I do this using WCF service? How do I get value back to the asp.net function? In serial port communication, the data is received in a separate thread.

P: n/a

Hi All,
I've written an ASP.NET application (webservice) that does simple serial
communications via the .NET 2.0 SerialComm object.
The application runs fine on my development machine. The problem is when we
try to deploy it to another machine we receive: ACCESS IS DENIED TO COM1 PORT.
We have tried unsuccessfully to get this to work. We have tried the following:
1) Assign the IUSR.... account to Administrators
2) We have actually had the local administrator account run the webservice
3) rebooted
4) stopped and restarted IIS - etc. etc.
We are unable to resolve this. Is there a special permission that the
account needs? Once again we are running XP Pro and it works fine in
development but we can't get it to run on this other machine!!!!
Also - we have implemented the same code using a regular client application
and it works fine (i.e. copied all the code out and put it in a simple
windows form and we're fine).
The problem is running it as a webservice. It does not work!
Any thoughts - comments are appreciated! Thanks!
