THE BTM410/411
13. ATSn? {Read S Register Value}
This will return the current value of register n.
For recognised values of n
Response: <cr,lf>As Appropriate<cr,lf>OK<cr,lf>
For unrecognised values of n
Response: <cr,lf>ERROR nn<cr,lf>
14. ATSn=? {Read S Register – Valid Range}
This will return the valid range of values for register n.
For recognised values of n
Response: <cr,lf>Sn:(nnnn..mmmm)<cr,lf>OK<cr,lf>
For unrecognised values of n
Response: <cr,lf>ERROR nn<cr,lf>
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 will be converted into a single byte before transmission to the peer.
Response: <cr,lf>OK<cr,lf>
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 will all pending data in the output rf
buffer be fl ushed 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 3 character
sequence \hh will be converted into a single byte before transmission to the peer.
Response: <cr,lf>OK<cr,lf>
