10/06   Here's a question for some genius guru out there.  I'm on a WAN
        using 3-com super-stack II net biulder 221 to connect an ethernet
        to a 56.6 connection supplied by the phone company and sent to
        server land.  Now when i connect a p.c. with a given i.p. add.,
        net mask, etc. it seems to work fine, but a MAC with the same
        info can only send data of less than 1.5K.  I.e. when packet
        splitting is involved, it fails.  Any ideas of what might be
        the problem?? (using mac tcp/ip and open transport versions 1.2)
        I know i'm asking for a lot here.  - crebbs
        \_ You need to use a REAL OS like AmigaOS or Linux which supports
           packet splitting in the latest patch!
           \_ Amiga eh? Now there's some stat of the art I'd like to get
              my hands on. At least they're better than Win95. What isn't?
        \_ Sounds like broken path-mtu negotiation.  Got an admin out there
           stupidly filtering out all icmp?  See if you can force a smaller mtu
           on your macs and that might fix it. -ERic
