Bad news Geva, the IIc port 1 is a printer port, incapable of input, only
output.  Guess you have to get your computer fixed.

WRONG!! Both ports are hardware identical. It's just that the firmware
has been configured to operate #1 as a printer port and #2 as a modem
port. Since I don't use the firmware for serial operations on the //c
(but will on the GS in the future), it doesn't matter what port you
use.

BTW- there was a bug in Z-Link with regard to using any slot other
than #2. This was very recently pointed out to me and I've fixed it.
The repost will go out Friday night sometime.
