Send file through serial port

[flowjob]

Hi,

 

I'm trying to send a text file through the serial port to a blood glucose meter. When using the hyperterminal, that comes with Windows, it works, but when I try do it on my own using C# it doesn't. How does the hyperterminal send text files using the serial port? And how can this be done using C#?

You will want to lookinto System.IO.Ports. Look on MSDN for VB/C# 'Code Snippets' There's a great example of sending data to the serial port and getting responses back. I will see if I can post a smiple sample tomorrow when I get to my home computer.

Thanks, no need for the samples. Got it working by adding \r at the end of each command.
