I am trying to read data from com1 and I am using the new serialport control.
I downloaded the script from microsoft that does a readline from the comm
port, but I keep getting the "operation timed out" error. I then will open
up HyperTerminal and connect and the output then displays? The arguments
appear to match up between my serialport control and what is setup in
HyperTerminal. Any help would be appreciated.
Thanks.

Here's my problem.
I'm using Visual C# 2005 Express for a small project that requires simple AT
modem commands to be sent to an external serial device. The device requires
2400 baud, no parity, 8 data bits, and 1 stop bit. Should be easy enough,
except that I cannot get the SerialPort component included with C# Express
to talk with this box.
I know the box itself is working correctly because a Visual Basic 6.0
application that I...

Hello all,
I would like to use the new SerialPort class in Visual C++ 2005
Express edition, but I am having problems adding my event handler to
the DataReceived event. In the header file I have the method that will
handle the event defined as
private: void SerialPortReceive_EventHandler( System::Object ^ sender,
System::IO::Ports::SerialDataReceivedEventArgs^ e );

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?

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 WriteToSerialPort(string what) and
ReadFromSerialPort(what).

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.
Here is my compilation command:
