Hi again,

Looks like I found the answer to my question - full-duplex on the
509B is indeed now supported. The file 3c509.txt included with the
new 2.4.19 kernel source explains in some detail the new features
added in with the v1.18c driver for the 3c509B and others. 8->>
Thankyou David.

Transceiver parameters '8' and '12' both enabled full-duplex
according to dmesg when passed to the kernel through an append
statement in lilo. However, the full-duplex light on my switch still
isn't activated. 8-<<

Given that the 3com 509B is pre-'N-way autonegotiation' can I expect
this indicator to light? Does it indicate that full duplex is not
quite operational? How can I test it and find out if it's active?
