Heheh... let me guess - the dialog only accepts three digits? ;-)

I had similar issues running a direct connection between two machines on
a LAN, although I was able to get 80kbps and above, using WP ECU 2.0 and
the 16-bit Cornell version.

Maybe you're hitting a limit set by the hardware you're using at either
end? My understanding is that CU is designed to not send more packets
than the receiver has said it can handle. Have you had a look at the
stats - are you getting dropped packets? Just and idea....

Hey, well if you can tell me how to get CU running under Linux I'm all
for it. CU and games are about the only reasons I need to use anything
other than Linux... ;-)

Apparently there is QuickCam support for 'nv' under Linux, and you can
run your own reflector to hook into other refs, which will handle
conversion of NV to cu.

Unfortunately I'm using a Videoblaster + camcorder so that doesn't help me
a lot... ;-(

Anyway, good luck and have fun playing with your T1!
