1.see Smart Messaging 2.0 for info, what the DMCP is

2.I didn't have success in changing menus via cable (without sending SMS).
  Here is example foogle funtion. You will see only "Nokia service update failed"

3.to change via SMS - read parts of email sent by Martin Lucina [mato@kotelna.sk]
-----------------------------------

1. First of all, use the OPER (Operator) services rather than the Nokia
   services. There's probably no reason why you couldn't use either but
   there may be extra hooks in the phone firmware regarding Nokia
   services that I don't know about.

2. Make sure that "Operator access number 1" and "Operator access number
   2" are set correctly in the services menu. The former should be set
   to the SMS centre the messages you send are going to come from
   (important, send yourself a test message and check it's details, some
   operators set the sending SMSC number to one different from the one
   you originally sent the message to). The latter should be the number
   of the MS you are sending the SMS from.

3. Don't send the messages as binary NBS messsages using the UDH. I
   haven't been able to get this method to work and besides, the //SCK
   compatibility header works just fine. 
   
   Also, while I haven't seen this, it's possible that if you send a
   message in binary format, the destination MS will reply in binary
   format. This makes the reply useless if you are sending from another
   NBS-aware phone, since the NBS router will most likely silently
   discard it (or try to forward it to the phones TTML/DMCP server,
   which won't help either). 
   
   If you send the messages as text, the replies I've seen also come
   back as text so you can retrieve them from the phone in the normal
   fashion.

One caveat I've noticed with sending NBS messages using the //SCK
compatibility header is that the NBS grammar in the Nokia SM spec
version 2 contradicts the grammar in the original Intel NBS spec. Nokia
says you can using either a newline or space as the delimiter after
"//SCK", it turns out that you _must_ use a space (as stated in the
Intel spec). Of course you can still stick a newline in afterwards.

I have attached a test file that will add two menu items that send SMS
messages to your services menu. I send this to the phone using

$ sendsms +6421XXXXXX < addsms

[...]

I've always been mad I know I've been mad like the most of us are             
Pretty hard to explain why you're a madman even if you're not mad
