When setting up my = external US robotics 56k modem using the kernel/pppd implementation of = ppp, I initially got silo overflow errors constantly. Even during = authentication or pings I would get them and the web was unusable. I had = the line speed for /dev/cuaa1 set to 115200 as I do on all the other = os's i run (windows 98, 2000, 2 distros of linux, beOS). After lowering = the line speed to 57600 everything works fine. My question is, shouldn't = my serial ports which are 65550A's (I think that's right) be able to = handle a line speed of 115200 without problems? Secondly, why am I only = getting these problems in FreeBSD? I understand that the other OS's = might not report these problems but whereas my modem in the other OS's = is very usable in FreeBSD it slows to a crawl at the higher line speed. = Oh, and by the way, I read through a bunch of archived emails and news = postings to try to find the problem. I tried enabling dma on the hard = drives and disabling usb stuff in bios. Both of which did not help. = There were problems with old computers at higher line speeds under heavy = load, but my computer is a celeron 333 and when i use top to look at = load it is always near 0. Any suggestions? I would really like to get = the higher line speed working because most documentation on setting up = modems suggests it.
