No, ESC[2J clears the screen(clear with home), ESC[J clears from cursor down(clear without home). Write a quick script and test it on Syncterm
if youwant to verify. I will try ESC[0J and see if ftelnet supports that code though, that would be great.
I've read that there has been some issues with ESC[2J not working in Windows. The ESC sequences that Nuskooler shared actually works. I tested it out on my end too. But I only used two of the 3 Esc codes that he used.
Esc[H - Move cursor to upper left cursor.
Esc[J - Clears from the cursor down.
Esc[H Esc[J
