I'm going to guess 60 MHz or so on the processor...I think that's what I saw on some IBM site. It's running AIX 3.something. I'm trying to connect to it using cu from my PC. It's set to 8N1 and 9600 like it's supposed to be, and I'm using a null modem cable, but shit still ain't right--I get a bunch of ASCII garbage when I attach to the port.
Well, sounds like the hardware is communicating. If you type characters in, does it do something? I think the problem is the terminal protocol; I don't think regular telnet supports it. I think it is trying to negotiate some stuff, hence the ascii crap. Look for a program that has the terminal settings that you need. The link I gave you should document the necessary protocols.
