what is the meaning of those commands in SerialTime example ?
#define TIME_MSG_LEN 11 // time sync to PC is HEADER followed by unix time_t as ten ascii digits
#define TIME_HEADER 'T' // Header tag for serial time sync message
#define TIME_REQUEST 7 // ASCII bell character requests a time sync message
return 0; // the time will be sent later in response to serial mesg
Where can I read about those commands ?
I google them and only the SerialTime example came up
I read time filefolder and I can't find anithing about those commands (with capital letters like:TIME_MSG_LEN)
