Serial Port

Greg21 · 08-06-2003, 03:51 PM

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

Greg,
Make sure your port speeds are correct at both ends. You may want to try 9600bps on both the terminal and Comm Port (ttyS#). If in doubt of the speed on the Comm Port, use the 'setserial' command. You can usually find a good example, of it's usage, in the /etc/rc.d/rc.serial file. And, as always consult your local man page for more info :-). Good luck!
