To send AT commands to a modem, you must first place the modem in AT command mode. To confirm
that you can send AT commands, enter sendat at. The modem will return OK or 0 if it is ready to accept
AT commands.

must repeat the sendat command.
This command does not verify the validity of AT commands. To verify the AT command execution result,
enable modem debugging on the interface. To view the AT commands sent to the modem, issue the E1
command to the modem.
