value too much can result in spurious interrupts. Leaving it too

This layer provides much of the groundwork for keeping track of

To configure this layer for use, create a modem_socket_config

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.
