I'm hardly expert in standard practices in this area, but I'm
under the impression that the cua* devices are for dial-out.
This may not be definitive, but I note the following in
/usr/source/linux/Documentation/devices.txt:
3 char Pseudo-TTY slaves
[...]
64 = /dev/ttyS0 First serial port
...
127 = /dev/ttyS63 64th serial port
[...]
5 char Alternate TTY devices
0 = /dev/tty Current TTY device
64 = /dev/cua0 Callout device corresponding to ttyS0
...
127 = /dev/cua63 Callout device corresponding to ttyS63
