[Haskell-cafe] ByteString questions

    1) I noticed there is no "open" function in Data.ByteString. So when I
call writeFile or readFile is there an implicit open?

    2) For both readFile and writeFile, the first parameter is of type
FilePath (which is of course alliased to just String). In any case, for
Windows and POSIX OS's like Linux can read and write to a serial device like
RS232 by specfiying the device path, e.g. /dev/tty01?

Thanks, Vasili
