Speed Packet Protocol The Radar message packet consists of 7 bytes @ 1200 baud, no parity, 8 data bits, 1 start bit. Messages are paced at 250mS intervals and are sent whether there is a target or not. Weboptions.c_cflag &= ~CSIZE; /* Mask the character size bits */ options.c_cflag = CS8; /* Select 8 data bits */ Setting Parity Checking. Like the character size you must manually set the parity enable and parity type bits. UNIX serial drivers support even, odd, and no parity bit generation. Space parity can be simulated with clever coding. green polywood adirondack chair
