Subject: [PATCH] Ignore SIGPIPE signals

If the remote end of a socket is closed between when an input character
is received from the serial port and when it is written to the socket,
tio will receive a SIGPIPE signal when writing the character to the
socket, which will terminate the program. To prevent this, ignore the
signal, which will cause write(2) to return -EPIPE, causing tio to close
the socket.
