4.1.1 Enabling Communications in C# for RS-232
Communications in Microsoft Visual C# are started with the COM port
initialized and then the port opened. Then a routine would be created
to send commands out the COM port, and another routine to receive
responses from the port.

Initialization Routine:
For example:
CommResult Connect( string comPort, int baudRate, Parity parity =
Parity .None)

Send Routine:
For example:
void SendCommand( Command cmd, string [] parameters, ref byte[]
buf)

Receive Routine: That is polled or interrupt called.
For example:
void ReceiveCommand(ref byte [] buf)
4.1.2 Configuring Communications in C# for RS-232
In order to configure the COM port object, first you must initialize it
in the COM port properties:
Settings
115200,n,8,1
Handshaking 0 – None
The following could be an example C# Code routine to initialize the
COM Port.
port = new SerialPort (comPort, baudRate);
port.Parity = parity;
try
{
port.Open();
}
catch
{
Console .WriteLine( "Error opening " + comPort);
}
