2 * Definitions for the CHU line discipline v2.0
6 * The CHU time code consists of 10 BCD digits and is repeated
7 * twice for a total of 10 characters. A time is taken after
8 * the arrival of each character. The following structure is
9 * used to return this stuff.
11 #define NCHUCHARS (10)
14 u_char codechars[NCHUCHARS]; /* code characters */
15 u_char ncodechars; /* number of code characters */
16 u_char chutype; /* packet type */
17 struct timeval codetimes[NCHUCHARS]; /* arrival times */
20 #define CHU_TIME 0 /* second half is equal to first half */
21 #define CHU_YEAR 1 /* second half is one's complement */
