Serial Port Communication in VB/C# .Net


I am working on an VB.Net application which I want to communicate to
external device using comm port (Serial Port) .

So for that first I am trying to simulate the communication on serial
port between two computers using HYper terminal on both the machines.
Both these computers are connected on serial port using DB9(f) null
modem (Cross) cable.

But I dont see any data transfer between these computers. Sometime I
am not able to type anything on the Hyperterminal window also.

Basically I need to migrate the legacy MSComm in VB 6.0 application to
SerialPort in VB.Net 2005.

I have checked that hyper terminal settings are correct in both the
I am not sure If I am doing anything wrong to simulate this serial
port communication between two computers.

Any help would be appreciated.
