Working off a fresh full install of Slack9.
I have a matrix orbital serial LCD, it takes ASCII from the serial port and displays it. So I tried to write directly to the serial device.
echo "foo" > /dev/ttyS0
I tried this for S0 - S9
Didn't work. Next i fired up minicom and played around in there for a while. Still can't get it to work. What am I missing? What needs to be done to get the serial port working under slackware 9?
Thanks, I don't use the serial port much and I'm clueless
