From man TIOCPKT:
"""
In packet mode, each subsequent read(2) will return a packet that either
contains a single nonzero control byte, or has a single byte containing zero
('\0') followed by data written on the slave side of the pseudoterminal."
"""
This CL implements only the data portion of packet mode, not the control bytes,
but that seems to be enough to get xfce4-terminal to work.
