AT&T style command [Urgent]

Hello,
I'm using a PIC UART's to communicate with a module using AT&T style
command, what i want to know is :
1- Can i use only TX and RX from PIC to send AT command
2- When sending a command like AT+BTIN, Is this equivalent to send
'A'+'T'+'+' ... characters from TX ligne ?
3- When can i fin application about using microcontrollers ti send AT
commands
Thaks.

1- Can i use only TX and RX from PIC to send AT command

Yes.

2- When sending a command like AT+BTIN, Is this equivalent to send
'A'+'T'+'+' ... characters from TX ligne ?

I'm not sure what command that is. I would suspect that when people say
send "AT" + something, they do not mean to send the +. For example,
ATDT1234567(return) will dial 1234567

3- When can i fin application about using microcontrollers ti send AT
commands

The "AT" command set is from Hayes modems, not AT&T. Do a Google search for
"AT command set" or "Hayes modem commands."
