A bidirectional line is quite difficult without a modem.
You would need some fancy software.
The problem is that unlike with the modem, carrier detect will
always be present. So each line, which as a Getty on it, will always
have the getty active.
Put two getty's at one another and it's real fun. The first asks for
a login, and the second does two, except that gets taken as a userid, and
then the word "Password:" is taken as a userid on the other system etc. etc.
You need a silent getty that doesn't print any prompt, and even then
it's tricky.
As the port is always open, you have to be able to tell between a getty
that has the port truly open and a user on the port. Otherwise you can't
know when it is safe to turn it around.
Sounds like a good TCP/IP with SLIP would be the right answer. But
very few tcp/ip makers include SLIP. I think SCO does, now.
