Some... this isn't direct from Diablo docs, but from a book I have that
lists lots of RS232 setups:
Diablo Systems, Inc: RO 630
Pin Function Direction
1 protective ground n/a
2 transmitted data from 630
3 received data to 630
4 request to send from 630 (note 1)
5 clear to send to 630
6 data set ready to 630 (note 2)
7 signal ground n/a
8 rec. line signal detector to 630
11 printer ready from 630 (note 3)
20 data terminal ready from 630 (note 3)
Note 1: Pin 4 is always on (high)
Note 2: Pin 6 must be on (high) before the 630 can receive data
Note 3: Pin 20 can be used instead of pin 11 for hardware flow control
