New To Serial Port Programming

[dilbert0610]

I have been asked to create an application that will take a text file containing lines of code for a CNC machine and send it line by line to a CNC controller.

The lines will have to be send through a serial port. I have a basic understanding of serial ports but starting my computer work after the internal modem days I have not done a whole lot of work with serial ports. I have read over the serial port control information on the MSDN but and still pretty clueless as to how to get started.

Are there any good examples of serial communication that I can reference for this? Or does anyone have anything they have created that I may take a glance at?

Thanks in advance.

To excercise coding the SerialPort class without equipment you can also connect a loopback to use for coding connection/writes/reads to yourself, the serial cable is very easy to short to make the loopback, see for example http://zone.ni.com/devzone/cda/tut/p/id/3450. Here is also a code tutorial I found when I searched for "vb.net serialport": Programming Serial Ports Using Visual Basic 2005
