Hi,
I'm experimenting with the Serial Port in VB.NET 2005. Although it isn't
that easy to get any feedback from my COM-port as I thought it would be...
How can I read all the Data that the port sends back?
I tryed with SerialPort1.ReadLine, but that blocks the application and takes
a lot of time (10 seconds!), I tryed SerialPort1.Read, but I have to read it
into a buffer and has to indicate the count, but how do I know this?

I'm trying to convert from a lot of invoked code to c# 2.0 SerialPort code.
I can't find a way to set fOutxCtsFlow to true (maybe CTSEnable?) and
fRtsControl = RTS_CONTROL_HANDSHAKE (RtsEnable?). Also, do I need to set
the handshaking? Below is the old and attempted new (that continually gets
a timeout error on read. I upped the read timeout, but it's way too long
NOT for it to be a handshaking or other issue than the readtimeout...

Hi,
In my application for PDA I use the serialport class to send data to a
navigation computer of VDO Dayton.
Everything works fine as long as it is connected to the nav-computer.
When the nav-computer is not connected to the PDA, the program hangs.
No exceptionerrors, no serialports error events, nothing.
Even if I set the WriteTimeOut property to 500, I still don't get any
messages.

Hello,
Someone can tell me why I dont get serial port events in a Service, I
created a separate Thread to open the port but no events are coming up (the
same happens when I use the timer component, using the System.Timers.Timer
it works fine)
tnx in advance

Hi Everyone,
I'm using the System.IO.Ports.SerialPort component to attempt to kill
an existing component opened by another application.
I use the following code:
SerialPort serialPort = new SerialPort ("COM1");
if(serialPort.IsOpen)

Hello,
I'm developing an application in VB.NET 2005 that communicates with a device
through RS232,
and need to send the following sequence of hexadecimal data to the device:
0xFF, 0x01, 0xC3, 0xE3, 0xFF, 0xFF.
That's the configuration:

Forgive me for stupid questions for I am new to serial IO programming.
I am developing an app that will need to communicate with a device via
RS232 protocol using a standard 9 pin serial cable. From what I
understand this can be accomplished relativly easy using .net 2.0
SerialPort component over a COM port.
My question: because most newer computers don't have 9 pin serial
ports (COM), can the SerialPort component use a USB connection...

I'm trying to send some printer commands (ZPLII) to an attached USB printer
using the SerialPort component. I didn't get very far at all. In fact I
haven't gotten anywhere.
The first problem I encountered is that a call to SerialPort.GetPortNames()
returns an empty string. In other words, NO port names are returned. I'm
not terribly knowledgable about ports but from the Hardware Manager I did
notice that I don't have the Ports and...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
