[section:GettableSerialPortOption Gettable serial port option requirements]
In the table below, `X` denotes a serial port option class, `a` denotes a value
of `X`, `ec` denotes a value of type `error_code`, and `s` denotes a value of
implementation-defined type ['[^storage]] (where ['[^storage]] is the type
`DCB` on Windows and `termios` on __POSIX__ platforms), and `u` denotes an
identifier.

`const `['[^storage]]`& u = s;`\n
`a.load(u, ec);`

[`error_code`]
[
Retrieves the value of the serial port option from the storage.\n
\n
If successful, sets `ec` such that `!ec` is true. If an error occurred,
sets `ec` such that `!!ec` is true. Returns `ec`.
