    Yes, it is easy to test TCP (ftp, telnet). I'm using a Linksys
    10/100 hub. I've tried versions of the module current with
    2.2.14 and 2.2.17 kernels, along with the 'current' and 'test'
    version of the driver from Becker's site.

    Very good point! I don't often power down my box and most boots
    try to load an unsuccessful module before I try to load a
    modified version. I deleted the tulip modules in /lib/modules/...
    and shut down *and* powered off before trying again. Unfortunately
    it did not help.

    (tulip-diag describes the card as being in half duplex mode and the
    box for the router says nothing about full duplex operation, so I
    believe that these are correct.)

    thanks,
    hank
