When trying to send a raw binary value using hexadecimal notation such as
"screen -X stuff $'\xB5\x62\x0A\x04\x00\x00\x0E\x34'", the 0x00 bytes are not
send at all. I checked it with an oscilloscope.

I suppose there is something related to interpreting the string as null. This
must work, plain C++ using a boost library is able to send raw 0x00.

This bug makes the tool not capable of using it to send binary data.
