Just copying files to/from the PC, I get a transfer rate of ~40K/sec. (X-SurfII set at half duplex).
Which brings me to my next question;
If the LAN should be set for Full Duplex and
If the WAN should be set for Half Duplex,
Then how does one configure for both?

PS:
I will try ttcp when I have the time to devote to it, I am quite busy with alot of everyday stuff.
