Paul,
Much as I hate to disagree .....
I checked Apple's tech site and had difficulty finding anything about serial
ports. However, there was an example of connection to an external modem.
On the external modem side, DCD was looped out and not connected to the Mac
at all.
Here is a definition of the Mac serial pinout taken from Imperial College's
support site:
Macintosh Mini 8 DIN plug (MCC-8)
---------------------------------
6 7 8
3 4 5
1 2
Pin Signal Name Description
1 HSKo Handshake out
2 HSKi Handshake in / external clock
3 TXD- Transmit data -
4 GND Signal Ground
5 RXD- Receive Data -
6 TXD+ Transmit Data +
7 GPi General Purpose Input (modem port only: can be set
by software to act as a second clock)
8 RXD+ Receive Data +
DCD is not used! Hence I still think a workaround really is needed for
diald.
