I was looking at the disasssembled TELCOM source today, and it seems there’s
almost a kilobyte devoted to looking up and dialing phone numbers that could be

handshaking and maybe even XMODEM once that (and ADDRSS and SCHEDL, another 333
bytes of dead weight) are ripped out of the ROM.
Has anyone tried anything like this? I know about HTERM, but I want to maintain
modem functionality and I don’t care that much about VT emulation.

There is LibROM https://sarahkmarr.com/retromodel100.html
The details are still quite different from your idea, isn't even
compatible with US models and ditches the modem support entirely because
UK hardware etc, but it's an example of successfully change the main rom
software more than just changing the date and fixing a tiny math bug.
