Ok, I've searched and searched .... can someone provide some info on how
to change the MTU on OS9.x? It does not appear to be changeable via the
TCPIP preferences. When I dump my prefs using DumpNetworkSetup I don't
see any prefs related to MTU. I see two pieces of software out there
that offer MTU adjustment capability - ipNetTuner and the Enternet
client.

IPNetTuner uses the SIOCSIFMTU ioctl (standard BSD as described by
Stevens in UNIX Network Programming) to set the MTU for the corresponding
named device. You'll probably want to contact Apple DTS for the API
details since they haven't been published (or you might deduce them
yourself from the dump ARP Cache sample).

Kind Regards,
