Yes, that seems most likely. Overflow can be tested for as well though, by sending large amounts of data over the link, in the absence of PPP. Careful counting will show what is lost. Although, if the link itself has no flow control, then some loss will always be a possibility. 10% of packets affected by loss seems a bit high, but I've no idea what the original poster's design threshold is. -- James Cameron http://quozl.linux.org.au/ -- To unsubscribe from this list: send the line "unsubscribe linux-ppp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
