Hi there,
I'm developing an application to catch OBD sensors' data from my car.
I connect it via a RS232 interface.
Now.
with HyperTerminal I can connect and send/receive data, but I'd like to do
this from inside my C# program.
Anyone can write down a very small (or tell how to do it myself) application
containing methods like...

Hello all,
Does anyone have an example on how to implement the new SerialPort Class in
VB.NET? I have been able to create the class, send (.WriteLine) to the port
and Read from the port but cannot figure out how to use the Events to tell
my program that data is available in the serial port buffer.
I have searched the internet and MSDN...

However, after I successfully read from the serial port, then close the connection, either when re-opening it (in the same instance or a new instance of my program) I get either an IOException "The Handle is Invalid" exception or...

Hello all,
I have a strange problem with the .NET serialPort class.
When I write some data to the serialport, not all the data is
immediately send: every once in a while, only ~50 characters of the 64
characters I'm sending gets send.
Then, when I do a write() again, the data gets send. This is
unacceptable behavior for my program.

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...

being setup correctly?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
