Another quick thought,
Putty (
https://www.putty.org/ )
has serial mode, and an AnswerBack for ENQ (Control-E).
You could try using that, although HPterm escape sequences will not work.

Subject: HP 3000/37 console
Does anyone know if a non-HP terminal will work as the console for a HP
3000 Series 37? The power-on self-test uses ENQ/ACK to speed sense, but
the manual also implies that it will sense speed from a <CR>. On my 37,
the TIC self-test passes up to the point where it talks to the terminal,
but fails to to speed sense.
