Customization in MSComm Control Usage

I have been trying to make a com port reader
for the purpose of reading a specified buffer
lenght. One PC is connected to the other
through Serial Cable 25 Pin connectors.

When I run the program through local loop,
it works perfectly fine.

when I try to send the buffer from one PC
and receive it in the other, the error occurs.

The problem is that, when the receiving
PCs' port is made open by me, and I run the
program, the error message says Port already
open but when I try to run the program
without opening the port, it says, action
only valid when port is open!!

I can't understand what is going on!

It is the final stage of my final year project and
I am stuck very badly in this.

In simple words:
I want to send a 50 byte buffer from
one PC to the receiving PC through a serial
cable.

Please help me as soon as possible.
