[lwip-users] pppMainWakeup: returned -1

[Shaun Jackman]

I compiled simhost with lwip 1.1.0 and ports/unix 2005-01-04. When I
run simhost I see the message
    pppMainWakeup: unit 0 sio_read len=1504 returned -1
repeatedly. Simhost does not respond to ping, although I do see tap0
in ifconfig.

Please cc me in your reply. Thanks for your help!
Cheers,
Shaun
