I have a similar problem. I'm making a PPP connection with jornada680
and a desktop pc. Then, ftp-downloading (pc->jornada) some large file 
the transfer will freeze at some point. I guess at average I can
download 1--10MB when freeze happens. The PPP link stays on however
and I can download the file if I'm using the reget command enough many 
times. I was using: "pppd /dev/scif0 115200 noauth local defaultroute"
and a miniroot.

I have no idea what causes this. I'm going to try SLIP if it works
better or not...Vesa
