I need a simple application that sends an RS232 command out the serial port every 60 mins, the command will be? Ctrl aI20100 this will respond with some data, I then want to write this data to a text file. ? If the file dont exist it must create it, if it already exists I want to append the data to the file.
It will need to support? multiple? COM ports, each come port will be assigned to a site name, this site name will be the name of the text file created. ? Each COM port setup will be polled once every hour and the data wrote to the files.
The interface needs to have a selectable location to store the files on the hard drive, and? remember? this location and settings? each time? the app is run. ? The app will need to be able to run in the task bar.
If one of the COM ports are not responding it will need to write an [url removed, login to view] file with this information in.
I would like this wrote in VB 2008
