I don't know exactly why, but you can for example read in the PPP-HOWTO:


[...]

  9.2.  Serial Port Names

  Historically, Linux used cuaX devices for dial out and ttySx devices
  for dial in.

  The kernel code that required this was changed in kernel version 2.0.x
  and you should now use ttySx for both dial in and dial out. I
  understand that the cuaX device names may well disappear in future
  kernel versions.
