As I wrote previously, Apple doesn't even have GPi on some Macs.
On the other hand, there is one solution. Digiboard makes 4 and 8 port serial
boards for A/UX that support both DTR/DCD and RTS/CTS (HSKi/HSKo). They come
with hydra cables that have real DB-25s at the ends!
I don't know how this works yet but I'm installing one tomorrow on Panix.
I'll let you know. (BTW, they also support Berkeley-style line control. So
the whole issue of dialin-dialout is moot.)
