We used to do this under 4.1BSD when all we had was UUCP.  It is all
a matter of asserting DTR (tied to the other computer's CD) at the
right time.  We had the DH driver hacked to do `passive', `active',
and `forced' or dialout opens:  The first would wait for CD, then
assert DTR; the second would assert DTR, then wait for CD; and the
third would assert DTR without waiting at all.
