If you want to run over serial, you should install pppd on the empeg to setup a point-to-point connection to the win98 machine. I don't know how to setup a ppp-connection from win98 directly on the serial line ( without a modem ), but there should be some workaround for it.
when the connection is made, you can use the command ipconfig/all or winipcfg under win98 to get the remote IP-address...
It's simpler to use zmodem copy from hyperterm though : on the empeg, cd to /drive0/fids and give command "sz *"
hyperterm should come with a dialog where to store the files on your PC.
