Details:

When I compile and run "contrib-1.4.1/ports/unix/proj/minimal" the default
message indicates:
Host at 192.168.0.2 mask 255.255.255.0 gateway 192.168.0.1

But if I try to connect with "nc -C 192.168.0.2 7" I get "No route to host"
error.

If add this line to low_level_init() before executing system(buf), then I can
connect to 192.168.0.2 and the program echoes my commands, as intended

  sprintf(buf, "/sbin/ifconfig tap0 inet 192.168.0.8 netmask 255.255.255.0");

Obviously, this is not the solution. Just to show that the program does not
respond to the IP connections it was supposed to.

mintapif.c is attached.
