The SIMPLEX flag is entirely hardware. There are some flags which tell the OS how to treat the adapter. They can be changed by buying a new adapter ...... SIMPLEX means, that the adapter cant hear himself talk during his transmissions. I have seen some obscure and dated IBM adapters which where able to listen while transmitting - there is the choice between ECHO and NOECHO. On ethernet the signal is quenched; on token rings it comes arround again - I think simplex is reminding you on this fact. All current ethernet adapters should show SIMPLEX, I guess. On AIX I can see the actual media speed via netstat -v. Orm To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
