I've written an application with a plug-in feature, and if a plug in doesn't respond quickly to a stop request, I call Thread.Abort() on its worker thread. This seems to work most of the time, but I recently discovered that it throws an ObjectDisposedException if the thread is aborted while it's writing to the serial port. With some USB-...
I have a C# application that uses the SerialPort object to establish a connection between another copy of the application running on another machine with BlueTooth capabilities. The program fairly constantly writes out some ascii data from the main machine, which is then received by the remote machine. The process goes fairly nicely (tho...
Pretty simple question this time around. I have an application that communicates with another copy of the application on another machines. One application sends a pretty constant stream of data, the other receives it. The code to send data looks like this (where serialPort is an instance of the System.IO.Ports.SerialPorts class in C# .N...
This is a major issue - I use a serial port in an application here and I poll the status of the attached device by opening and then closing the port again. If the device fails, SOMETIMES the SerialPort.Close() - method NEVER returns and this is really a show stopper. The worst thing is that even shutting down the application using the ...

I could not find a book on WinCE programming. Are all the libraries and header files for winCE same as for windows (WIN32)? I am programming in C. I want to use serial port communi...
So I've never used javascript before. I was sent this code that interfaces with a tty device. I need to port this code to python but there's not a single comment in the entire thing. Is this an internal javascript class or whatever javascript uses? var IEC = new IECPort('/dev/ttyS2'); ...
Hello, I am trying to port (or rather customize) a pure Linux application to OS X Snow Leopard (10.6.4). It is an application that sends a binary to a target hardware over the serial port. The app is almost running but i am hit with an interesting problem with the serial port writes. With all the same settings as Linux (115.2k is the b...
Hello, I want to use xpcom to connect Mozilla Firefox to a serial port. The final result should be an xpi addon that can be installed on various environments (cross-platform Windows/Linux with Firefox 3.*). Where should I start?

i am writing a method which sends a particular packet and gets an answer back from an electronic device. I am using system.io.ports with rtsEnabled = true. The problem is that when entering the application the received packet is altered. I am monitoring what is being received using eltima and the packet received by eltima and that by...
Hi, I've written a Generic Handler so I can access my server's COM port through javascript. I'm doing this, because I'm writing a Web Interface to an ESP-88 from BOSE, for internal use. The code must be configurable, and I added routines for both TCP/IP support and RS232. In a desktop app, the code runs fine, but in an ASP.net 4.0 App...

I am afraid that several terminologies in my question are wrong. Please bear with me and correct me wherever I am wrong. I have to write a library/program that will provide set of function to operate a card reader attached at Serial Port. Like to eject card that was inserted in it, user will simply have to call in his code, for example,...

The cable and the applications are same as in the working an...
I'm writing a small piece of code that would determine which serial ports on a computer are free for connection. This is done by looping through the different serial ports and calling the Open() method. If an exception occurs, this indicates that the port is unavailable. However visual studios is telling me that I'm not disposing of the...

I'm having some issues trying to figure out Async communication on a serialport object and was hoping to get some help. I'm still learning Async stuff so be gentle:) I basically need to make sure that the buffer isn't full prior to writing to the serial port and also all data has been read before any more data gets written to avoid ...
