I got this example from a radio modem using the hayes protocol:
- by the user using the terminal (using AT commands), examples:
AT<CR> _________________it is 0x41 54 0D
or:
AT<CR><LF> ____________ it is 0x41 54 0D 0A
response:
<CR><LF>OK<CR><LF> ___it is 0x0D 0A 4F 4B 0D 0A
Another source:
There is a standard set of response strings that the modem sends back to
you to tell you the results of an AT command.
They have the format CRLF, "response code", CRLF.
A few of the more common response codes are listed below:
