Very Computer

Does anyone have any experience connecting a Sun SparcStation to a
Northern Telecom SL-1 Asynchronous Data Option (ADO) digital telephone?

My objective is to have the Sun answer the phone, but the phone 'rings'
in a very non-standard way (i.e. instead of a ring, it _says_
'Phone is ringing. Pick up? (Y/N)'). Is there a way to control such a
device from a serial port on a Sun? Ultimately, I want it to answer the
phone and present the caller with a login prompt.

Any advice would be highly appreciated.

Thank you,
