[Mono-list] SerialPortTest

[sojan]

the code is as follows please have a look

using System;
using System.IO.Ports;
 
public class SerialPortTest
{
	public static void Main(string[] args)
	{
		SerialPortTest myTest = new SerialPortTest();
		myTest.Test();
	}
 
	private SerialPort mySerial;
 
	// Constructor
	public SerialPortTest()
	{
	}
 
	public void Test()
	{
		if (mySerial != null)
			if (mySerial.IsOpen)
				mySerial.Close();
 
		mySerial = new
SerialPort("/dev/ttyS0",9600,System.IO.Ports.Parity.None,8,System.IO.Ports.StopBits.One);
		mySerial.Open();
		mySerial.ReadTimeout = 400;
		SendData("ATI3\r");
 
                // Should output some information about your modem firmware
		Console.WriteLine(ReadData());  
	}
 
	public string ReadData()
	{
		byte tmpByte;
		string rxString = "";
			
		tmpByte = (byte) mySerial.ReadByte();
 
		while (tmpByte != 255) {
			rxString += ((char) tmpByte);
			tmpByte = (byte) mySerial.ReadByte();			
		}
	
		return rxString;
	}
 
	public bool SendData(string Data)
	{
		mySerial.Write(Data);
		return true;		
	}
}
