| 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. |

| Decreasing this value can help increase data throughput when high |
| baudrates are used. 278us is 4 bytes at 115200 baud. Decreasing this |
| 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 |
| object and pass it's reference to modem_cmd_handler_init() along with |
| the modem_cmd_handler reference from your modem_context object. |

| help |
| 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). |

| bool "Generic modem socket support layer" |
| help |
| This layer provides much of the groundwork for keeping track of |
| modem "sockets" throughout their lifecycle (from the initial offload |
| API calls through the command handler call back layers). |
| To configure this layer for use, create a modem_socket_config |
| object with your socket data and pass it's reference to |
| modem_socket_init(). |
| Note that the modem socket uses runtime allocated file descriptors |
| reserved from the fdtable, for which the max count is set using the |
| Kconfig option POSIX_MAX_FDS. Make sure to update this value as both |
| the modem sockets and the POSIX_API, if used, share them. |
| |
| config MODEM_SOCKET_PACKET_COUNT |
| int "Maximum number of stored packet sizes per socket" |
| depends on MODEM_SOCKET |
| default 6 |
| help |
| 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. |
