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.

You're welcome.  :-)
