Hi, 
I wish to use pppd to connect to my ISP with an ELSA Microlink 56k USB. 
Under the NetBSD 1.5 snapshot the USB Modem is detected and even handels the local/remote IP. :-) 
But if I try to ping local/remote address, Tx/Rx blinks but there is no echo. route show hangs on the ppp0 entry. 
 
My Board is a K7V with USB shared with a DEC-Tulip card (sorry have only one unshared port) 
 
Linux has problems with this sharing and gets no echo on the tulip, Be seems to have no probs with this.
