Learning Calterm etc

[Mrkentee]

I have INSITE and an inline 5 that I have no problem using. I have Calterm on my computer, but no idea how to use it. I’ve had someone access my ecm twice via Team Viewer. Once to program a new ecm when the old one failed. And once for tuning. That’s how I got Calterm.
I would like to know how to do that myself if it happens again. And to understand how to transfer a file with email, etc.
I know the file is in my computer, but don’t know how to access it, or read it.
How could I learn that?
Thanks
