(This > is, historically, sometimes a problem on VAXen.) After some more tests I am consistently seeing around 580 cps on a direct 9600 baud line between a uVax running VMS and a 68000 Unix box. Windows=7 PKTSIZE=64. I have never seen 90% bandwidth utilization. My 3B1 at home running at 1200 baud always gets around 100-120 cps. How are you computing bandwidth utilization? (c * 8) / b where b = baud and c = chars. per second? c taken from xferstats in /usr/spool/uucp/.Log -- Dave Arnold dave@arnold.UUCP {cci632|uunet}!ccicpg!arnold!dave
