Because modern serial ports can suck, so do serial cables. I wouldn't trust anything other than a high-end serial card to handle the data it's not something that's given much thought in modern motherboards. > Once Eric gets TESTFRAME going, then we can start collecting samples. This is for live testing since I can control the GPS signals I can expect the same data to be received by the clock and then ntpd. I will need a way to dump that info but it's easy.
