now im starting huper terminal, 9600, com1, 8,n,1, connected xx:xx:xx and
i can't type anything, pressing on keys don't display nothing, but schematic works fine with logo manager as f-bus cable.
? how it could be? logo manager works, does it meen cable is OK?

after few hours i have sucesfully send msg from hyper terminal. now some other questions
1: is it so necessary to use pic on mbus? if so, my project has to be double pic'ed
2: finaly project uses a 9210 mobile, but seems like communicator dont recognize pic on mbus (debug led on pic remains off all the time)? 6210 works, but now i need to do the same with 9210.. any suggestions?

If you follow the thread from the top, you will find out how. Anyways, just type the commnds that are relative to the phone being used: AT+CMSG etc...

Look the manual of your phone and then type them in your terminal. You can also set your modem to ASCII and not PDU format which is more convinient.

Lotondo: like on the schematic abowe, u have to use pic connected to m-bus and if its working good, phone will connect to terminal...
