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).

Using the built in control SerialPort, I can correctly open a port, and
write something to it (commands like "ATX" and other worked fine from
HyperTerminal), but I can't read nothing, using SerialPort.ReadLine(). This
method always generates a Timeout exception.

What's wrong?
To send, for example, the "ATX" command through the serial port, I use
SerialPort.Write("ATX"), but nothing seems to happen.

Hope someone will help me soon!!!
