The application can be set to either default to a specific COM Port
or the End User can be allowed to choose one for the particular PC.
After initial configuration the following could be an example C#
code routine to set up a transmit array, to build and send out a
message to the COM port.
Void SendCommand( Command cmd, string [] parameters, ref byte[] buf)
{
Array .Clear(buf, 0, 128); // Clear a transmit buffer.
len = BuildCommand(cmd, parameters, buf); // Build Message.
port.Write(buf, 0, len); // Send buffer to COMM Port.
lastResult = CommResult .CmdGood;
}
For the receive routine, the reply routine would be polled when the
receive buffer is filled with messages. Then a user routine would be
needed to parse the reply messages.
void ReceiveCommand(ref byte [] buf)
{
// Wait for response
Array .Clear(buf, 0, buf.Length); // Clear Receive Port
port.ReadTimeout = 50;
port.Read(buf, 0, 128); // Read COM port char. By char. Into
// buffer.
DecodeResponse(buf); // Decode message in buffer.
}
