Does anyone have a reasonable description on how to use the Appletalk 
Data Stream Protocol?  The DSP is mentioned in an older Appletalk book as
a protocol that provides a continuous full-duplex error-checked data stream
over Appletalk.

I am trying to put together a simple virtuial serial port that will allow
one Mac to talk over Appletalk to a computer or modem attached to another
Mac's serial port.  I'm also looking into putting together a simple "chat"
type utility for Appletalk.

Yes...I know I could write my own socket/protocol drivers but then I would
have to handle a lot of the error recovery/timeouts on my own...if DSP is
available I can avoid all that re-inventing the wheel.
