Note: All modem control signals are single ended (un-balanced) with RS-232 signal levels.
Technical Note : Please terminate any control signals that are not going to be used. The most common way to do this
is connect RTS to CTS and RI. Also, connect DCD to DTR and DSR. Terminating these pins, if not used, will help
insure you get the best performance from your adapter.
