Good day
thank's to you

for Jeckson
I have used terminal them to Bray version 1.9b optimal suggestion.

for Jan
I have tried to send through terminal a message with commandos AT with
full success.

Now I'am ready to create a program that pressing on the keyboard connected
to microcontroller that it sends a message.

Which passages are necessary?
I try to list them:
to set the transmission speed,
I use a quartz to 12.00Mhz on my board, in the tests with commandos AT I was set up to the
19200 and other parameters then to write commando AT on the serial.
Is possible read the result of a sent command the cellular?, to verify if the result is positive.

But it is better than I attend your councils.
