Staring the IIGS modem port pin-out inside the hardware reference 
manual, I see that this pin-out:

1	DTR
2	HSK1 (Handshake in)
3	TX Data -
4	GND
5	RX Data -
6	TX Data +
7	GPI
8	RS Data +

I'm more used to the full 25-pin pinout and am trying to understand 
there the following signals are used:

DSR
CTS
DCD

Is this all handled in software?
