There isn't an API function to interrogate the current status - line status
is one of the things where the state changes are important, not the state
itself. Instead line status changes are indicated by a callback function
set using cyg_io_set_config(..., CYG_IO_SET_CONFIG_SERIAL_STATUS_CALLBACK,
&callback_info, sizeof(callback_info));

where the callback_info has type cyg_serial_line_status_callback_t (see
serialio.h). The code's in serial.c.
