["Aage Rettvin" <aage.rettvin@c2i.net>]

With reference to received  advice on the newsgroup I have looked into the
pin-assignments as given in the French Apple IIc .dsk site:

----> I've constructed a new shielded five-lead cable with the following PIN
assignment setup:

DIN-5F    ----> DB9F

#3  DTR           #6
#5  TX             #2
#2  GRN          #5
#4  RX             #3
#1  DSR           #4

-----> The cable is not working properly as there lacks some modifications
according to feedback from  from  delfs@apple2.com  who wrote following:

---->How should the 1,6 and 4 be 'shorted' on the DB9F,  the leads
themselves or directly on the socket.  Pls. update me on how to do this as I
am not familiar with the terms used here!
