Linux test program

Hello,
I’ve made some first steps to a linux velbus interface. Just wanted to share, maybe usefull to someone.
Little note, don’t expect it to be that structured code since I’m not used to program in C.

code: leachy.homeip.net/velbus/velbus.c

at the moment I use an usb interface (vmb1usb) wich in my system is recognized as /dev/ttyACM0, this is the default interface in the program, an other interface can be given at the command prompt (ex ./velbus /dev/ttyS0)
compiled with gcc (gcc -o velbus velbus.c).
remark: when using the usb interface, you 've to let the system know what the default baud rate is otherwise it will not work (command:stty -F /dev/ttyACM0 9600 )

Very interesting project
