When I set the port open property of the
receiver to true then error says, port
already open.
When I set the port open property of the
receiver to false then action is only possible
when port is open!

I am stuck and need the solution urgently.

Scenario is that I have to send a data buffer
of a specified lenght to the serial port.
the data will be transferred to other PC
through serial cable and the receiver will
receive the buffer when it is ready and
sent by sender.


A problem stays like a challenge till
I find the solution to it.
