I'm having an issue with a powershell script that I would like to use for configurating a barcode scanner. I've been able to get most working, but I think because I use rather simple writelines, readexisting etc etc I'm not always getting the right answer of the device (the barcode scanner) nor am I sure that I send all lines.
So when I'm searching stackoverflow (or Google for that matter) I'm getting a lot of stuff about the datareceivedhandler etc, but I'm not sure how to get my script and the eventhandler to work. I've never used any eventhandlers in powershell so my ability to understand those are somewhat limited. I know they are a lot used in .net, but from my understanding I cannot literaly copy paste them from a c# code. Can someone help my on the way (I don't need a whole rewritten script, but just :
- this is how you start the eventhandler datareceived
- this is how you do a writeline with above method
- this is how you do a readline with above method
I'm sorry if the question is out of order, then you may close it off course.
