Agreed, but as soon as device setup is through with your device (thus the "properly configured character device") and your reading program behaves nicely (which I'd expect GR's file_sink to do), just reading from a character device should work, if I'm not mistaken.
However, this brings us to a new question: "serial" doesn't really say what kind of interface we're talking about; there's a whole lot of bytes that you can not send over a 1980's style UART as used for the RS-232 peripheral on PCs, and thus the data that comes in over that has to be decoded first; you could write a block that converts these bytes to bytes, or, and this is more likely, you already have software that does that, and writes the result to a file, or prints it on standard output. You could then connect the output of that to GNU Radio, e.g. using a named pipe.

Hi Julian,TTY I/O on Unix is a bit weird. You'd have to open it, and configure it (into RAW mode for one).
this really depends on how your serial data gets into your PC, but assuming you're on linux and have the data coming in over a properly configured character device (ie. something that appears as /dev/ttyS* or the like), you could just use the file source and open that device.
Greetings,

Hey there! i'm working on a proyect of comunications and i need to get my
serial data stream into gnuradio companion, so i'm looking for a block (2
actually) that can make this work, i tried to install pyserial and
gr-pyserial but repository is down, so i'm looking for alternatives, that
make me skip programming it myself (becoues of my low programing skills ),
so i though serial port is pretty comun, some one else had to build it
before, if you know some blocks which could help me i would be very
thankfull
