1200bps. The black box has or had a label saying it was only good to
2400bps anyway...

Yes we could... There's an echoing of characters (atH0/atH1), then an OK.

Yes, perhaps with a DECserver. Whether that would be more reliable is

modems can be reset on a dropped DTR, if they're not completely crashed -
that could help, too.
