6.3.15 ATX<string>{Send Data in Local Command and Connected Mode}
This command is used to send data to the remote device when in local command and connected mode.
The parameter <string> is any string not more than 24 characters long. If a non-visual character is to be
sent, then insert the escape sequence \hh where hh are two hexadecimal digits. The 3 character
sequence \hh is converted into a single byte before transmission to the peer.
Response: <cr,lf>OK<cr,lf>
6.3.16 ATY<string>{Send Data in Local Command and Connected Mode}
This command is similar to ATX in syntax and functionality, except that the string is only copied to the
output RF buffer. Only when an empty string is presented are all pending data in the output RF buffer
flushed out.
The parameter <string> is any string not more than 24 characters long. If a non-visual character is to be
sent then insert the escape sequence \hh where hh are two hexadecimal digits. The three character
sequence \hh is converted into a single byte before transmission to the peer.
