hello again. Sorry about the delay; I don't monitor this board all that
closely.
So, it appears that you have wireless access on your home network with
your PDA and you have the software on it needed to do a WOL request.
Under a linksys wireless router, the settings I use are as follows;
The MAC address of my network card; you can find this by typing' ipconfig
/all' at the command prompt.
This link tells you a little more about getting the MAC address for your
NIC.

Next is my IP address. For this I use my real IP provided by my ISP.
For the subnet mask you want to use 192.168.1.255 (this may be different
under another companies router; likely 192.168.*.255). We use 255 here
b/c the computer doesn't actually have an IP until we turn it on, so we
have to broadcast to all channels (?). The only computer that will
respond to this broadcast is the one that has a MAC address that matches
the one you provided. Therefore, this can be done to a unlimited number
of machines by just changing the MAC address.
There should be an option to send on the subnet, rather then the
internet. Of course, if you are on a wireless network outside your home,
you will have to send the request through the internet. I am yet to
explore this option; I have only ever woken my machine from within my own
home network (I am a little new at this myself, if you hadn't noticed).
There is also a port option that I have set to 9. I have in turn
forwarded this port to my machine, but this really doesn't make sense b/c
that machines IP doesn't exist until it is on, so in theory the port
forwarding shouldn't be required. If anyone else can shed some light on
this topic, I would be interested. I'll post this link again, so that
you understand the GUI that I am looking at.

Hopefully the WOL interface on your PDA is looking for the same info; I
see no reason it would not be.
Now, the more important part (I guess I like to do things a little
backwards). Will your PC support this?
Let's go back to the 'ipconfig /all' that you typed in at the command
prompt to determine the MAC address of your NIC. This same command will
tell you the name of the LAN card that you have (I've been referring to
this as a NIC). This is the one that I have;

Not quite sure what tells you that this is WOL compatible, so you're on
your own here. I know that this one is. I've read that more recent
cards will be.
Do you know what kind of motherboard you have? It will be listed in the
device manager and, like the NIC, if it's fairly recent it will supprt
WOL (we may have already touched on this in a previous post; I don't
remember). To make sure that it has been turned on in the bios, you will
have to restart your computer. One of the first things that you should
see come up on your screen during the restart is 'press del to enter
setup'. Press the del button at this point. If this is not the case (as
I believe some dell machines will not let your enter the bios), you will
just have to assume that it is turned on.
Lastly, the machine has to be in a soft off state for all this to work.
This simply means turning off the computer with the windows 'shut down'
command, as you would normally use. If you were to hold down the power
button to shut down the machine, this WOL service may not respond.
Hopefully all that will get you a little closer. This took me a while to
figure out myself, and I'm still not sure if it even works outside my
home. Very nice control to have however; especially if you do any
travelling, as you have the power to turn your home comptuer on and off
from anywhere.
Good luck
Andrew
