To send the commands, use cron(8).  You'll have to decide to either
use the /etc/crontab file, or submit any and all cron commands via the
crontab(1) command.

As for the script, it's something like:

#!/bin/sh
echo "ats0=0&w" | tip <whatever you would use here>

to turn it off, and

#!/bin/sh
echo "ats0=1&w" | tip <whatever you would use here>

to turn it on again.

Don't forget to chmod +x both scripts.

Never trust an operating system you don't have sources for. ;-)
