Hey all, just had a quick question. I just purchased a super serial card for my apple iie platinum, and was wondering about the serial cable. do I use a straight-thru cable or a null modem cable?

It depends on what is on the other end of the cable........
A null modem cable would be if you are attaching it to another computer directly serial port to serial port.
I've never heard them referred to as straight through cables before.
I thought they are referred to as simply a serial cable or modem cable, but I never pinned one out before either....

It would be connected to a wimodem232

Then start with the straight thru cable
If that doesn't work try this
SSC -------------------------- Modem
---------------------------------------------
GND 1 ----------------- 1 GND frame ground (this line is OPTIONAL)
TXD 2 ----------------> 2 TXD transmit data (from SSC to modem)
RXD 3 <---------------- 3 RXD receive data (from modem to SSC)
RTS 4 ----------------> 4 RTS request to send (for hardware handshaking)
CTS 5 <---------------- 5 CTS clear to send (for hardware handshaking)
DSR 6 <---------------- 8 DCD data carrier detect (from modem)
GND 7 ----------------- 7 GND signal ground (for all signals but pin 1)
DCD 8 (leave unconnected!)
DTR 20 ----------------> 20 DTR data terminal ready (to hangup modem)
Have the ends of this cable labelled "SSC" and "Modem", as it will not work correctly if plugged in backwards

Gracias. One more question: do I set the super serial card to "terminal" or "modem"?

modem

I have used a standard RS232 modem cable as well as just a gender changer (direct plug-in) with my SSC on the //e.
