| This driver allows modem drivers to communicate over UART with custom |

| This driver allows modem drivers to communicate with an interface |
| using custom defined protocols. Driver doesn't inspect received data |
| and all aspects of received protocol data are handled by application |
| work method provided. This driver combines abstractions for: |
| modem interface, command handler, pin config and socket handling each |
| of which will need to be configured. |

| value too much can result in spurious interrupts. Leaving it too |
| high can reduce data throughput. |

| This generic command handler uses a modem interface to process |
| incoming data and hand it back to the modem driver via callbacks |
| defined for: |
| - modem responses |
| - unsolicited messages |
| - specified handlers for current operation |
| To configure this layer for use, create a modem_cmd_handler_data |

| This option sets the maximum number of parameters which may be |
| parsed by the command handler. This is also limited by the length |
| of the match_buf (match_buf_len) field as it needs to be large |
| enough to hold a single line of data (ending with /r). |

| modem "sockets" throughout their lifecycle (from the initial offload |
| API calls through the command handler call back layers). |

| object with your socket data and pass it's reference to |
| modem_socket_init(). |

| As the modem indicates more data is available to be received, |
| these values are organized into "packets". This setting limits |
| the maximum number of packet sizes the socket can keep track of. |
