Hi,
I need some help connecting a black box with a Macintosh serial port.
This box is currently being used on an IBM-PC connected with a home-made cable.
The plug on the IBM-PC is a DB-9 and the connection on the black box is a DB-25.
The cable setup is as follows:
DB-9 DB-25
DCD 1 ---|
RTS 7 ---|
CTS 8 ---|
DTR 4 -----|
DSR 6 -----|
RD 2 --------- 2
SD 3 --------- 3
GND 5 --------- 7
I'm trying to use this black box on a Macintosh with a mini-DIN 8 plug.
What I need to know is if it is necessary to do the same fooling around
connecting DCD, RTS and CTS as well as DTR and DSR on the 8 pin plug. I've
read the bit in the Family Hardware Reference about connecting the RxD+ and
the GND and reading and sending the data through TxD- and RxD- but am unsure
about what needs to be done with the rest of the signals.
Any help would be greatly appreciated,
Terry.
