tx enable with RTS signal #14

Your software is very easy and lite. I am using it with an ftdi cable and a MAX485 chip for half duplex communiccation (most common in plc's) The idea that i had was to use the RTS signal of the serial port to enable transmission on the MAX485 chip as it defaults to recieve mode.
