HP-IL with HP 82163A Video Interface

[institches]

Thanks for your prompt reply. I tried your example and I can display the @ character on the screen as you described. I take it the 7 refers to displaying the character on the screen?
I now have a better understanding of the codes but I still don't understand the manual when it says "Escape Sequence 'EC A' Character Codes 27 65 Moves the cursor up one line..."
I am reading this from the 82163 manual.
