Serial port
5. Leave Sharing Mode at the default, None.
6. (Optional) For Label, enter a label that will be used when referring to this port.
7. Enable Altpin to use the Altpin feature. Altpin is disabled by default.
This feature should be enabled when you are using a modem and an 8-pin cable and you need
CD (Carrier Detect). When enabled, the DTR on pin 1 drives DCD.
If altpin is disabled, 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.

RS-232
