you may have some trouble with that. i managed to get my hands on one here at
caltech, and we tried to tweak it but here's what happened:

it powered on, sent  ^PCd (or something similar) and then sent ^F's once a
second after that. it blasted out a ^H when it went into setup mode, and ^PDx
when it went back to terminal mode (actual sequences may vary).

i think what is going on is that the 2622 is using some esoteric and HP250
specific codes to communicate with the host. the terminal inside is kind of
neat, it is a Z80 system with 6 rom sockets (2 used in mine) and 16K of ram.
i'm getting ready to disassemble the code and figure out how the hardware is
accessed, then reprogram it for vt52 (easy) and later vt100, maybe vt220, it
has underline and dim, and full ascii; a real nice display.
