So, my "new" terminal, the Magis Club, does has a 9600 bauds, 8 data bits mode, and I can actually see what I type on the Oric on the minitel (when I set it up in this mode), but typing on the Minitel keyboard does not seem to send anything to Oric Term 380, so I did your TX-RX strap, and all I'm typing his appearing on the Oric, so I guess that means the Receive pin is properly identified and working. So, just to be back in context, here are the connections I had identified on the Oric RS232 interface:
1 - Black - DCD -> 7
2 - RED - TxD -> 2
3 - Green - RTS -> 4
4 - Orange - GND -> 3
5 - Blue - DTR -> 6
6 - White - RxD -> 5
7 - Brown - RxC -> 1
8 - Copper - GND -> Shield
and how I wired these to the DB-9 connector:
+--------- (Red) 1 - DCD -> Oric 1: Black [Data Carrier Detect]
| +------- (Black) 2 - RX -> Oric 6: White [Received Data]
| | +----- (Gray) 3 - TX -> Oric 2: Red [Transmitted Data]
| | | +--- (Orange) 4 - DTR -> Oric 5: Blue [Data Terminal Ready]
| | | | +- (Brown) 5 - GND -> Oric 4: Orange / Oric: 8 Copper
| | | | |
1 2 3 4 5
6 7 8 9
| | | |
| | | +-- (Yellow) 9 - RI -> Oric ??? [Ring Indicator]
| | +---- (Blue) 8 - CTS -> Oric ??? [Clear to Send]
| +------ (White) 7 - RTS -> Oric 3: Green [Request to Send]
+-------- (Green) 6 - DSR -> Oric ??? [Data Set Ready]
I did not connect RI, RTS and DSR, because I had no idea what they should connect to on the 7 different wires (4 and 8 are both ground) of the Oric interface.
