That was what I was thinking.  If there are no modem init strings or dial
strings, hopefully it will just connect.  I guess I'll see.

I checked the archives, and the general consensus seems to be that one can use
modem eliminators to connect two AS/400s together.  I assume the same would
work for an AS/400 to a Linux box.  Perhaps short haul modems would work also

Actually, it is a RISC box.  I'm not sure how fast the 2612 controller can go,
but for emulation it doesn't have to be super-fast.  Another option would be to
pick up a 2617 ethernet or 2619 token ring card plus the 7108 expansion gate.
I've seen the token ring cards on e-bay for very cheap.  The expansion gate I
saw online somewhere for $175.

I don't know if I would call it hell-bent, but since I bought it and had it
shipped, I'm going to get it connected to my linux box one way or the other.
