Hi,
As other people with the same problem may find this bug report, I will
just write down the workaround I found, sufficient for my usage and
somehow based on http://ubuntuforums.org/showthread.php?t=2263143.
Adapt the following script to match the output of the barcode scanner
and what you want to be displayed:
#!/bin/bash
# infinite loop
while true; do
# read input number by number
while read -n1 char; do
if [ "$char" = "0" ]; then
# we print keycode 19, which means "0"
xdotool key 19
lineReturnDone="false"
elif [ "$char" != "" ]; then
# we print the number using his keycode
xdotool key "$(( char + 9 ))"
lineReturnDone="false"
else
# we print one line return
if [ "$lineReturnDone" != "true" ]; then
xdotool key "36"
lineReturnDone="true"
fi
fi
done < /dev/ttyS0
done
Here, note the workaround for the "line return" (if I understood well,
my barcode scanner sends two ASCII "NUL" character after the numbers,
but I want a line return instead). Note also that it will only write
output to X server, not to TTY.
Finally, start this script when X session starts.
Best regards,
Yvan
