2 * print PPP statistics:
3 * pppstats [-a|-d] [-v|-r|-z] [-c count] [-w wait] [interface]
5 * -a Show absolute values rather than deltas
6 * -d Show data rate (kB/s) rather than bytes
7 * -v Show more stats for VJ TCP header compression
8 * -r Show compression ratio
9 * -z Show compression statistics instead of default display
