Here are the relevant details.  Note: the pin number diagrams are
looking at the BACK of the plug (or directly at the socket in the
computer).

IIc end (DIN-5 male)           ImageWriter II end (Mini-Din-8 male)

5       1                         8 7 6
 4     2                          5 4 3
    3                              2 1

1  DTR (flow out)              1  Handshake out     5  RxD-
2  TxD (data out)              2  Handshake in      6  TxD+
3  Ground                      3  TxD-              7  not used
4  RxD (data in)               4  Ground            8  RxD+
5  DSR (flow in)


The cable pinout is as follows:

IIc       ImageWriter II
 1 ------- 2
 2 ------- 5
 3 ------- 4 and 8
 4 ------- 3
 5 ------- 1


Note: the same cable can be used as a "null modem" cable between a IIc
and a IIgs or Macintosh.
