NOTES:
Altpin should be turned on when using this cable so that DTR will drive DCD (standard usage).
If altpin is turned off, the hardware signal on RJ45 pin 1 becomes DSR instead of DCD. This
alternative can be used if DCD is not required, and DSR is needed instead.
This cable utilizes the RTS signal of the PC terminal emulator for hardware flow control
(RTS/CTS).
