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.
