- I think they're the same as the GS's (same controller chip, anyway), which
- are, per the Apple IIgs Hardware Reference, 2nd edition:
-
- Pin Signal Description
-
- 1 DTR Data Terminal Ready
- 2 HSKI Handshake In
- 3 TX Data- Transmit Data -
- 4 GND Ground reference and supply
- 5 RX Data- Receive Data -
- 6 TX Data+ Transmit Data +
- 7 GPI General Purpose Input (usually used for DCD)
- 8 RX Data+ Receive Data +

- The serial port should be able to it, since both machines use a Zilog 8530
- controller chip. The GS does it with no problems. I'm not sure if the IIe
- card does any additional emulation, like to make it look like a Super Serial
- Card.
