Serial Port Comunication in C#

Hello, It's the first time I make a post here, everyone tells me that is the best place to ask for help..
I'm making a project in C# (Windows Forms) about an intelligent house with facial recognition, fingerprints detector, an alarm system and access to the DVR (videocameras manager) and stuff like that.

The problem is that I have an electronical interface that I made myself which reads from the alarm's sensors and sends strong electrical signals using the Serial Port (USB Adapter). (For example, to turn on the lights in a room, the air conditioning, or reading data from the sensor of the alarm)
I used to have it working with a VB6 code that I'll give you next in another project..
It's made using the MSCOMM32.OCX library, I didn't make the code, but I understand it..
The thing is that I need to convert this code using the Serial Component used nowadays in .NET which has different properties that I can't assimilate.

This is the code in VB6:

Private Sub Form_Load()
//MScomm Configuration.
MSComm1.CommPort = 1
MSComm1.Settings = "9600,n,8,1"
MSComm1.InputLen = 0
MSComm1.Handshaking = comNone
MSComm1.RThreshold = 1
MSComm1.SThreshold = 1
MSComm1.DTREnable = True
MSComm1.PortOpen = True

outputs = 0
Text1.Text = outputs
MSComm1.Output = Chr(&H31)
MSComm1.Output = Chr(outputs)

command= &H37
MSComm1.Output = Chr(command)
Timer1.Enabled = True
index = &H80
Text2.Text = 253
Text3.Text = 200
Text4.Text = 400

End Sub

Private Sub MSComm1_OnComm()

If MSComm1.CommEvent = comEvReceive Then
input = MSComm1.Input
 ......
End Sub

I just need to know what are the similar events and properties to configurate the Serial component..
It would be REALLY helpfull..
Thanks in Advance, Lucas.
