The Door Lock
Hi All, The modem has now been replaced with the arduino and the small 5v relay board. It's working for now, but it's a hack and not even properly boxed up. [TPG] has already modified dispense to suit it. If it breaks, I'll let you keep the pieces. For posterity, here are the super-sekret settings and commands: Serial over USB connected to merlo, 115200 8n1 Type "2;" and it will respond with "1,The UCC door is alive;" Type "4;" and it will respond with "1,Opening door;" , keep the lock open for ten seconds and then say "1,Locking door;". The command codes are strange numbers because I hacked the CmdMessenger [1] library example to do the job. I've found using picocom to check it is easier than minicom. The following command* will start picocom with the correct baud rate and a command character of x: `picocom /dev/ttyUSB0 -e x -b 115200' Bob
