//HOW TO CREATE A SIMPLE FRAME
char outbuf[128]; //Buffer for frame
char* cmd = “SET”; //ASCII command
int link = 0xff, pos=0; //0xFF for control channel
int len = strlen(cmd); //Calc. length of ASCII command
//Generate packet
outbuf[pos++]=0xbf; //SOF
outbuf[pos++]=link; //Link (0xFF=Control, 0x00 = connection 1, etc.)
outbuf[pos++]=0; //Flags
outbuf[pos++]=len; //Length
//Insert data into correct position in the frame
memmove(pos cmd, len);
pos += len; //Move to correct position
outbuf[pos++]=link^0xff; //nlink
