I'm trying to talk to GRBL directly. Here's what I'm doing:* ssh to lasersaur* service stop driveboardapp.sh* screen /dev/ttyO1 57600* reset atmel (pulling Jumper auto_reset)Unfortunately screen only shows scrambled output.I guess the serial device is correct, otherwise I wouldn't see anything, right?Is the baud rate right?
