FC3 Serial Port Camera Problem

[Jeff Trefftzs]

Hi,

I share my machine's serial port between my dial-up modem and my digital
camera, using a mechanical switch.  After upgrading to FC3 from RH 9 I
no longer seem to be able to download photos from my camera.  I thought
at first that this was because of incompatibilities between gtkam (the
RH 9 camera app) and gthumb (the FC 3 camera app), so I reinstalled
gtkam.  But no luck.  I have reset ownership and permissions on the
serial device (/dev/ttyS1) to allow me to twiddle with it (permissions
are 666, and I own it), but I still can't access the camera.

Another interesting problem is that I cannot use stty to even read the
serial port settings:

[jeff at thoth ~]$ stty -F /dev/ttyS1 -a
stty: /dev/ttyS1: Input/output error

The modem works with no problems.  Can anybody help with the camera
angle?  What's the best way to configure a serial device in FC 3?

Thanks in advance,
