"talkd" problems with 386i and SPARC

[Monty Andro]

I'm attempting to use "talk" between a sun 386i and SPARC station which
for some reason is not working.  I get the following error message on the
SPARC station when it responds to a "talk" request from the 386i:

	Unable to connect with initiator: address family not supported
 	by protocol family (47)

Can anybody explain this ?  Is there a compatibility problem with the 386i
and SPARC ?  Any information would be greatly appreciated.
