sorry... what does it mean : Gnokii

I don't think so... I'd like to send an sms with a mobile phone. I have
MBUS - PC and FBUS - PC cable for Nokia 5110, and I 'd like to write a
program for windows which can send SMS throught the mobil (like Nokia Logo
Manager).

For this I need FBUS and MBUS protocol documentation. Because throught FBUS
and MBUS you need to communicate whit frame's , I have some doc about FBUS
:

Serial Communication

Speed: 115.2 kbps
Bits: 8
Parity: None
Stopbits: 1

Unlike the 21xx series and Nokia Cellularware, data is sent over the FBUS
which has both Rx and Tx lines.

Basic Packet Format

In a similar manner to the 21xx protocol. Packets sent from the 'phone must
be acknowledged by the PC via a special packet and vice versa.

Most communication takes the form of:

PC sends some type of "request" or command packet
6110 sends an acknowledgement
6110 sends some response to the request packet
PC sends acknowledgment
Format of packets from PC:
+--+--+--+----+--+---+----------+-+--+--+----+----+
|1e|00|0c|type|00|len|...body...|n|sq|0?| chk |
+--+--+--+----+--+---+----------+-+--+--+----+----+

type: some indication of message type:
( 1, 2, 4, 10, 11, 13, 14, 64 seen)
len: length in bytes from following byte to sq inclusive
n: if this packet is part of a group (i.e. long sms) indicates
how many more messages, including this one, there are
sq: packet sequence number,
least significant nibble: incremented in range 0..7 for each
new packet
most significant nibble: ? seems to be normally 4, but appears
to be 0 if this is not the first packet
in a group. 6 has also been seen
0?: 0x00, only included if len is odd
chk: 16 bit xor of all preceding 16 bit words
.
.
.

thanx for your help....

regards

Xor

ps.: sorry for my bad english...
