Three result codes are monitored after an AT command is sent to the modem. When a result code is
returned, it will be checked. If the code is not the normal result code ("OK", "CONNECT 9600/REL4",
"CONNECT 2400/REL4", in words), after a fixed time of waiting to send, the following retry processing
will be repeated 2 times to send the AT command again and waiting for another result code.
The receive monitoring time and send wait time for each sequence are shown below.
Note
The hexadecimal equivalents of sequences numbers are given in parentheses.
