It was my understanding that the cua* devices were only used for call out devices and not standard serial device. So the UPS should have used ttyS* in the first place. As for use of cua* devices and a standard see the Changes file in the 2.2.x kernel documentation under 'General Information': "Also, please remember that cua* devices are now obsolete. Switch to the corresponding ttyS* device instead (e.g., cua0 -> ttyS0, cua1 -> ttyS1, etc.)."
