For this, it simply has to call brlapi_enterRawMode(), then brlapi_sendRaw() and brlapi_recvRaw(), and finally give control back thanks to brlapi_leaveRawMode().
Special care of the terminal should be taken, since one might completely trash the terminal's data, or even lock it! The application should always check for terminal's type thanks to brlapi_getDriverName().
The client can also make brltty close the driver by using brlapi_suspendDriver(), and resume it again with brlapi_resumeDriver(). This should not be used if possible: raw mode should be sufficient for any use. If not, please ask for features :)
