Read Serial Port - Visual Basic 2010

Mar 18, 2011

I got an Arduino hooked up to the PC and would like to read the serial port of it. I read the serial port in Visual Basic with com.Readline, but it won't read everything. It looses around 2-3 lines that were sent over the serial port to the Visual Basic code. They get "lost".

Error In Serial Port Data Capture Program In Visual Studios 2010?

Apr 11, 2012

I'm trying to make a rs232 serial data logging program, that accepts a 12 bit hex RFID tagID from an RFID module. My end objective is to save this RFID tagID into a database and assigned to a person for a personnel management system.I had to use button3 to add the value of the variable 'msg' into textbox1 because I was getting the following error "Cross-thread operation not valid: Control 'TextBox1' accessed from a thread other than the thread it was created on". It is a temporary workaround.When I do press button3, I get the incomplete hex number, instead of "4C00A2C82A0C", I get "A2C82A0C", and sometimes I get random digits like 1,A,C etc etc.

Public Sub OpenPort()
Try
If SerialPort1.IsOpen Then
SerialPort1.Close()

C# :: Read Serial Port Control Line States With .net?

I'm working on a project where I need to trigger an event when a switch is closed. It is my understanding that it is possible to use the control lines on a serial port and read whether the switch is closed or not. I've found a schematic of how to connect the switches to the pins, but I have not been able to find any example code on how you can read the state of the switches.

Cannot Correctly Read Bytes From Serial Port Consistently

Jun 4, 2009

I have a timer control that sends data to a hardware every 3 seconds. I sent 6 bytes of data. In return I am expecting 8 bytes of data in DataReceived event. First time I send 6 bytes of date, in DataReceived event, I get the expected 8 bytes. Then in next 3 seconds, again the expected 8 bytes of data is received. But after that I find that DataReceived is fired 2 times: first time I get 6 bytes and then I get 2 bytes. After that I again get 8 bytes as expected. So in short, 2 times I get 8 bytes as expected and 6 bytes and 2 bytes and again 8 bytes. This pattern is repeating continuously. Why? Is there any reason why I cannot get all 8 bytes everytime? Note that the code is in vb.net 2008

Code in button btn_Start ()
'Set serial port parameters
x.PortName = "COM1"
