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.
