Reading the Sensors
Scale
Talking to the scale is straight forward. Usually send a short character string to the scale and listen for a reply. For the Adam Equipment: echo "G\r\n" > /dev/ttyS0 read -t 1 SCALE < /dev/ttyS0
To use the Cisco Linksys WRT160NL wireless router to talk to the My Weigh HD300 scale, first detach a process that sleeps for a second and sends a carriage return. Then read the data. The detached bit sleeps for a second, allowing the read to get latched onto the serial port, and then sends the command, which promptly returns data. 'sleep 1;echo -e "\r" > /dev/ttyUSB0' & read -t 3 SCALE /dev/ttyUSB0.
