The "BOTHER" baud rate constant is not handled properly in asio

[Steve Soule <sts11dbxr@…>]

In the file boost/asio/impl/serial_port_base.ipp, in the functions boost::asio::serial_port_base::baud_rate::store and boost::asio::serial_port_base::baud_rate::load, the baud rate constant "BOTHER" is not handled in either switch statement. As far as I know, this constant, along with the termios fields c_ispeed and c_ospeed, are the only way to set and get an arbitrary baud rate (rather than one of the Posix baud rate constants like B9600) on Linux. So if the user requests a baud rate not listed, such as 250000 baud, the store functions incorrectly rejects it; and if the currently set baud rate is not one of the ones listed, the load function incorrectly fails to return it.
