     Here is snip from FAQs. It comes from Steph's and Gist's
Apple IIc .dsk Archive site at ...

http://www.chez.com/apple1/Apple2cDskArchive/tech/Transfert.htm

which also has a nice pic showing the connectors.

     Below is the pinout for a IIc NULL modem cable for use with the
ADT disk image transfer utility. It shows signal names and signal
directions. 

     Both 9 and 25-pin numbering is shown for the PC connector end. 
For the IIc plug, DIN-5 pin numbers are listed with traditional 
Apple pin numbers in parenthensis ... 
  

  DIN-5M            Dsub9   or    Dsub25 
 (Apple)            9 pins        25 pins 

 4 (2) TXD     -->  2 RXD         3 RXD 
 5 (4) RXD     <--  3 TXD         2 TXD 
 2 (3) GND     ---  5 GND         7 GND 
 1 (1) DTR     -->  6 DSR --,*    6 DSR --,*
