[Boost-users] boost.asio: win_iocp_serial_port_service::open changes broke FTDI support

Hello, the changes to win_iocp_serial_port_service::open in commit c113adc19004770d945672009b3d26f9498099cd broke at least FTDI 4232H but probably all FTDI support for me. SetCommState(handle, &dcb) in new line 99 fails with error code 57. Reverting the commit seems to recover correct behaviour. Kind Regards Michael
