When i execute ./PiGatewaySerial, it prints on the screen values read from sensors, but
it doesn't write anything on the virtual serial device /dev/ttyMySensorsGateway

$ sudo ./PiGatewaySerial

instead, if i read from /dev/ttyMySensorsGateway i obtain only the first
message by the gateway, nothing else.

$ sudo cat /dev/ttyMySensorsGateway
0;0;3;0;14;Gateway startup complete.

$ ls -al /dev/ttyMySensorsGateway 
lrwxrwxrwx 1 root root 10 nov  5 16:32 /dev/ttyMySensorsGateway -> /dev/pts/0

$ ls -al /dev/pts/*
crw-rw---- 1 root tty  136, 0 nov  5 16:32 /dev/pts/0

c--------- 1 root root   5, 2 gen  1  1970 /dev/pts/ptmx

if i understood anything i think i should find all the messages from remote nodes in /dev/ttyMySensorsGateway but it isn't working like this.
Can you help me please?
