3.5.4 Access to VXC Auxiliary Serial Port
Each port of the VXC card has a corresponding auxiliary device named
cuaV. The auxiliary device cuaV behave is very similar to serial device ttySV
except DCD signal identify.
A serial port will fails to open when the DCD signal is OFF and closing
automatically when DCD signal is OFF. But the auxiliary serial device will not to
check the status of DCD signal if ON when open serial port and not closing
serial port automatically when DCD signal is OFF. The auxiliary serial device will
be useful with dialing-out modem that fails to assert DCD signal when there is
no one called into it and there is no carrier. The cuaV device was once used for
dialing-out and ttySV used for dialing-in purpose traditionally.
