Thanks to Udo de Boer, Elle van der Molen, Aaron Siebert, Selden Ball, Larry
Clegg, David Hull, Blake Roberts, & Tim Brown for their responses.
I was pointed in the direction of the man pages for fddi_config. The DEFPA
supports a full-duplex mode, but this is dependant upon the hub/switch at
the other end of the fibre cable. fddi_config -d for my adapters shows
this:
johlos:excalibur> sudo fddi_config -i fta0 -d
fta0 ANSI FDDI settable parameters
Token Request Time: 7.9872 ms
Valid Transmission Time: 2.6214 ms
LEM Threshold: 8
Restricted Token Timeout: 1000.0000 ms
Ring Purger State: Purger off
Full Duplex Mode: Enabled
Full Duplex State: Idle
johlos:excalibur>
Which seems to support that the card can be Full Duplex, but that with the
hub we have that is not possible.
It was also suggested to me that in some instances, a FDDI network is
similar to a Token Ring topology. The fddi_config display seems to support
this as well.
Thanks again for those who replied. While it doesn't seem like I'll be able
to squeeze any more data through this existing hardware, I've learned a lot
while trying to do it.

Subject: Setting a DEFPA FDDI card to full duplex?
Is it possible to set these cards to full duplex?
The current entry in /etc/rc.config is:
IFCONFIG_5="192.168.0.55 netmask 255.255.255.0"
Is there anything we'll have to do at the SRM prompt to enable full-duplex?
Or are these cards always full-duplex.
Thanks,
John Losey
