wake on lan

I have a MIPS-based router running proprietary linux system with shell
access. It contains almost only busybox. I want to use wake-on-lan
function, unfortunately the ether-wake utility is not included. Is it
possible to do this with the basic utilities included ? These are:

arp flash logread sort arping fping losetup start.sh ash free ls syslogd
auth ftpget lsmod system awk ftpput md5sum tail boot.sh getbin2.sh mkdir
tar brctl getwww2.sh more tc bunzip2 grep mount tcpdump busybox gunzip mv
telnet bzcat gzip netstat test cat head nslookup tftp chmod hostname ping
top chown ifconfig pppoe-server.sh tr clear ifstat pppoe.sh traceroute
connect.sh init ps udhcpc cp insmod pwd umount cut ip qos.sh uname date
iptables reboot uptime dd iwcontrol reload vconfig df iwpriv
reload_connect.sh vi dhcp.sh iwpriv-example renice vnstat disconnect.sh
kill reset watchdog dmesg killall rm wc dumpleases klogd rmmod webs echo ln
route wget expr load-test.sh sed wpa.sh fgrep logger sh zcat

It would be very complicated to compile anything for the router.

Unfortunately there is not something like /dev/eth0 device, where I could
send a magic packet (whose format is known and simple)

IS there a way how to do it on this simple stubby system ?

Thanks for any idea,
MB

Of course there is - it is a network device, yes ?
The WOL magic packet is sent to the device's MAC address, and has
nothing to do with TCP/IP.

If the router has this ability (which I *very* much doubt) then sending
the magic packet is all you need to do.

If you mean sending a WOL packet *from* this device (but you're not
saying that), the same applies: construct the magic packet and netcat it
out of the interface.

Yas, I want to send the packet from the router. Do you see netcat in the
list of available utilities ?
