Not that I'm aware of, at least generally speaking. This is specific to the IBM/Intel blade servers I've been working on some compatibilty issues with. The blades provide access to the serial port via a Serial-Over-LAN internal connection, but the BMC/BSMP on each blade is too slow to take 19200 baud without flow control and convert it into UDP packets without getting out of sync during heavy output (like booting). Putting the pager in lets me advance one line at a time which keeps the display from turning to mush. -- Doug White | FreeBSD: The Power to Serve dwhite_at_gumbysoft.com | www.FreeBSD.orgReceived on Sun Jun 05 2005 - 05:26:14 UTC
