Pil-io serial and remote keyboard

[coitboy2000]

Just a general question about the DISPLAY IS command. If I use the pil-io and set DISPLAY IS to the serial device, everything i type on the hp-71b is shown in real time on the ascii video terminal. However, if I use an arduino with a tft screen and a virtual ILDisplay (Tobies ILDrive software modified by me) nothing appears on the display until I hit the enter key on the hp-71b. Does this behaviour seem correct ? I wonder whether the CMT Display showed the hp-71b input in real time on its screen ?
