	Best of luck contacting an authorized Apple dealer or even
Apple Computer directly. Several weeks ago I tried contacting both, 
on several occations, and no one even knew what an "Apple II" computer
was, let alone anything concerning the free Apple IIc upgrade(s).
According to a clipping from GEnieLamp A2, the free upgrade offer 
expired May 3, 1995. The upgrade codes were ODL660 in the United States
and ODL299 in Canada, but I doubt they'll do you much good today.

	You can check if your Apple IIc has the serial port timing
problem. If you look at location C7 on the motherboard, you'll find
either a black 74LS161 TTL chip or a silver oscillator with a MHz 
rating printed on it. If you have the latter (oscillator) your IIc
has "good" serial ports. There were also two ROM firmware upgrades,
one for UniDisk 3.5 support (ROM 0) and the other that corrected a 
bug with terminal mode (ROM 4).

If you know when your IIc was manufactured or bought, these dates 
may help you determine whether you'd need an upgrade. (btw, all these 
dates, codes and part #'s are from memory, but I think I'm close :)
You can also check the ROM version of your Apple IIc by simply 
typing "PRINT PEEK (64447)" from the Applesoft BASIC prompt,
which will report back '255', '0', '3', '4' ('5' is the IIc+).

IIc's with "bad" serial ports:  April 1984 to November 1984
IIc's with original ROM 255:    April 1984 to August 1985
IIc's (mem-exp) buggy ROM 3:    September 1986 to late-1987
