Pil-io serial and remote keyboard

[J-F Garnier]

The DISPLAY IS operates differently on video displays, printers and other devices.
On printer devices, the line is sent to the device only when ENDLINE is pressed. On the other devices, the characters are sent just as they are keyed in.
There are other small differences, the details are in the DISPLAY IS description in the HP-IL user manual.

The original ILPer code (and Tobie's code) assigns a printer identifier (AID) to the display, whereas the PIL-IO has an interface AID, this explains the difference.

This is only true on the HP71, the HP75 DISPLAY IS doesn't make such differences.
