Hi, i'm developer, im writing a C# code to communicate with a Fiscal Printer
(Argentine) throw serial port. I have a problem, my communication is
Asynchronously and i need to simulate a synchronously communication, i mean,
like this.

System.IO.Ports.SerialPort x = new ....
x.Open();
x.Write("SOME COMMANDS");
x.ReadeUntilEnd(),
x.Close();

the problem is that i dont have this kind of think, the serial port
communication is Asynchronously. I cant figure out how to do this.

Thanks a lot
