HP-IL with HP 82163A Video Interface

[institches]

Hi,

I'm am a bit of a novice when it comes to this hardware but I tinker with it as a hobby.

I have an HP 82160A Interface Loop plugged into my HP41 and connected HP 82163A video interface. I have read in the manual about controlling the video interface with Data Byte messages in the form of excape sequences that are interpreted as instructions. There are no examples in the manual so I am struggling to understand the syntax/use of these codes. Any help would be appreciated.

Kind regards,
Gary
