Reading Data From Serial Port

[Magic8Computing]

Hi,

I have writen web sites before but have been asked to create a VB program, but dont know where to start so hoping someone can help me.

I need to create a program that sits waiting for data from the serial port which is attached to a set of scales, when the scales are triggered they send the weight of the object down the serial port to the pc that then writes the data to a text file and then waits for the next weight to be received, and continuous to run until stopped at the end of the day.

I hope someone can help.

Regards

Matthew

If you need to append to a text file, there are many examples on the web of how to do it. Search the following using your favorite search engine: vb.net append to text file
