As you've got some output there's a chance that it's nearly right, but
the SGI 9-pin serial port has a different pinout to a 'standard' 9-pin
serial port :-
The DB-9 female serial port connectors, which are found on the
CHALLENGE and Onyx systems, have the following pin assignments.
\ 5 4 3 2 1 /
\ 9 8 7 6 /
Pin | Name | Description
2 | TD | Transmit Data
3 | RD | Receive Data
4 | RTS | Request To Send
5 | CTS | Clear To Send
7 | SG | Signal Ground
8 | DCD | Data Carrier Detect
9 | DTR | Data Terminal Ready
Also make sure you don't have the keyboard plugged in.

You'll have to google for what that might mean.
