Calling System.IO.Ports.Serial.BytesToRead causes the program to close no
exception or error message is produced.

The following code reproduces the problem:

using System.IO.Ports;
using System;

namespace ConsoleApplication1
   class Program
      static void Main(string[] args)
         SerialPort serialPort = new SerialPort("Com4", 19200);
         int bytesToRead = serialPort.BytesToRead;

when run
before is printed to the console
after is not.

Reproducible: Always

Steps to Reproduce:
1. Compile the sample code using visual studio 2008
2. run using mono 2.4 on windows
3. see that the call to BytesToRead closes the program.
Actual Results:  
"Before" is printed to the console "After" is not printed, no exception or
error message is produced.

Expected Results:  
"Before" should be printed "After" should be printed. The program should not
close when executing serialPort.BytesToRead
